Question 3.
Indian Federalism and American Federalism are different. Do you agree?
Answer:
The Indian Constitution follows the federal system. This is what article 1 states: “India that is Bharat shall be a Union of States.” When India became free on 15 August 1947, the integration of the Princely, States became necessary. Our Federation did not come into existence through an agreement among existing States. It is a creation of the self-identity of the Indian people through the Constitution. The American Federal system came into existence as the result of an agreement among 13 colonies. Today America is Federation of 50 States.

The content of the 7th schedule is the three lists – Union List, State List, and the Concurrent List. On subjects mentioned in the Union List, the Parliament makes the Laws. It has 97 subjects. The most important subjects of the nation are in this list. The State List has subjects over which the States can make Laws. It has 66 subjects.

Over the subjects mentioned in the Concurrent List, both the Parliament and the State Assembly can make laws. It has 47 subjects. If any subject is not mentioned in the State List or Concurrent list, the Parliament will have the power to makes laws on that subject.

Question 6.
Critically examine the Indian Federalism.
Answer:
India is a Federation. All the features of a federation are found in the Indian Constitution.

  • Written and Rigid Constitution
  • Division of Authority
  • Independent Federal Judiciary

The Indian Constitution stands for a strong federal system. It created a strong federal system. The following show strong Central control:

  • All the most important subjects are in the Union list.
  • Governors are appointed by the Centre.
  • The Centre has the right to declare emergency.
  • The Centre has Residuary Powers.

Question 7.
Name the Commission that was appointed to study the Centre-State relations
Answer:
Sarkaria Commission

Question 8.
Evaluate the Centre-State relations in India.
Answer:
The Constitution is merely framework of Federalism. It is the political processes that supply the flesh and blood to it. Therefore the changing political processes are the most important factor that influences Indian federalism.

Demand for administrative autonomy: Many States of India are clamoring for greater autonomy. Often this causes rifts between the Centre and the states. The role of Governors and President’s rule: The role of Governors has caused many rifts between the Centre and the states. Often the Governors have to work as yes-men to the Central Government. Presidential rule in case of Constitutional Emergency is also a matter of conflict.

Demand for New States: This is another headache for the Federalism. For example, the demand for Telangana State.
Inter-State Conflicts: Sometimes these conflicts grow to such levels that federalism itself is threatened.

Question 9.
There are States in India that demand autonomy. What are the major demands of such States?
Answer:
Many States and Political Parties demand more autonomy for States. But autonomy means different things to different States and Parties. By Division of authority what some States want is more powers to be given to them. Many States and Political Parties demand more self-rule for their States.

Another demand is that States must have their own sources of income and they should have greater control over their natural resources. Some States wanted autonomy so that they can control their resources.

A third demand is that Centre should not interfere with the State administration. The States can’t tolerate the intervention by the Centre. The fourth reason for self-rule is linked to cultural and language matters. The opposition to Hindi in Tamil Nadu and the imposition of Punjabi in Punjab are causes of protest. The domination of the Hindi speaking States over the other States often causes rifts. Some States protested saying that Hindi was being forcefully imposed on them.

Question 10.
Inter-State Conflicts are common in India. Explain with examples.
Answer:

  • River-Water Conflict
  • Boundary Conflict

River-water conflicts often become serious as they affect the drinking water and water for irrigation.
Examples are Kaveri Water conflict, Mullaperiyar problem.

Boundary problems also exist in many States. Although the States were formed on linguistic basis, there are many linguistic minorities living in the boundary areas. Example, the conflict between Maharashtra and Karnataka regarding Belgaum.

Question 11.
Which Indian State has got special status according to the Constitution?
Answer:
Jammu-Kashmir (Article 370).

Question 12.
Write down the years in which the following States were formed:
Kerala, Punjab, Sikkim, Goa, Uttaranchal, Nagaland, Jharkhand
Answer:
Kerala — 1956
Punjab — 1966
Sikkim — 1975
Goa — 1987
Uttaranchal — 2000
Nagaland — 1963
Jharkhand — 2000

Question 13.
There is an opinion Governors are responsible for aggravating the Centre-State Conflicts. Do you agree? Explain.
Answer:
I don’t fully agree. A Governor is appointed by the Central Government. Governor is the head of the State Executive. Governors being Central Government appointees often clash with the State Governments. In the matter of imposing President’s rule and the dissolution of the State Government, there often develop rifts between the Governors and State Governments. But it would be unfair to put the blame of bringing problems to Indian Federalism on the Governors alone. There are some other reasons too for the Centre-State Conflicts.

Question 14.
Match the following:

A B
Residual Powers Article 356
Authority to dissolve the Government Inter-States Conflicts
State Reorganization Commission Cyber laws
Jammu Kashmir 1954
River Water Conflict Article 370

Answer:

A B
Residual Powers Cyber laws
Authority to dissolve the Government Article 356
State Reorganization Commission 1954
Jammu Kashmir Article 370
River Water Conflict Inter-States Conflicts

Question 15.
What is the relevance of Article 356?
Answer:
Article 356, which empowers the President to dissolve the democratically elected State government, has been often criticized. The first time it was used in Punjab in 1951. Before the election of 1967, the Article 356 was used 8 times. Three times it was in Kerala. By 1998, this article was used nearly a hundred times.

Question 16.
Point out the major topics of inter-state conflicts in India.
Answer:

  1. River Water Conflict
  2. Boundary Disputes

Since water is need for drinking and also for irrigation in the States, the overwater conflicts between States become highly complex. Examples are the Kaveri River water conflicts and the Mullaperiyar River Water conflicts.

There are also boundary conflicts between States. Although the States were formed on the basis of language, there are linguistic minorities staying in the border villages. For example, there is the conflict between Maharashtra and Karnataka about Belgaum.

The Sanchi Stupa is located on a hill in a small village called Sanchi Kanakera. This place is 20 miles north-east of Bhopal, the capital of Madhya Pradesh. Sanchi Stupa has different constructions and on the whole, it looks like a crown. Here we can see a temple built in the 5th century BC and many other historical monuments and also a huge mound. The Sanchi Stupa was built by Asoka in the 3rd century BC. During the time of the Sungas (183-72 BC), this was further developed.

HSSLive.Guru

Question 16.
Who are the ones who tried to take away the eastern gate of Sanchi? Why?
Answer:
The Sanchi Stupa was discovered in 1818. Europeans of the 19th century were greatly interested in this – Stupa. The French wanted to exhibit the eastern gate of Sanchi in a museum in France. They tried to get permission from Shajahan Begum, the ruler of Bhopal. But they failed in their attempts. Some English people. also tried such methods. In the end, both the French and the English had to satisfy themselves with the plaster cast of the Stupa.

Question 17.
Who protected the Sanchi Stupa? Write the names of two Patrons.
Answer:
Shajahan Begum and her successor Sultan Jahan Begum protected the Stupa. They spent a lot of money in the maintenance of this ancient monument. Sultan (This is just a name and not a position) Jahan Begum (1901-1926) took great interest in the matters related to Sanchi.

She donated money to build a museum and a guest house there. It was by staying in this guest house, John Marshal wrote volumes about Sanchi. To publish the writings of John Marshal also, Jahan Begum sanctioned money. John marshal dedicated his books to Sultan Jahan Begum.

  1. The protection and maintenance of the Sanchi monuments were possible because of the discretion and foresight of the rulers of Bhopal.
  2. It was a great fortune that they were made safe from the greedy eyes of railway contractors, builders and the Europeans who wanted to take them away to Europe.
  3. Sanchi is one of the most important Buddhist centres in India. The discovery of this completely upset our earlier concepts and understanding of Buddhism, This place is now under the protection of the Archaeological Survey of India.

In Iran Zaratushtra, In China Confucius, in Greece Socrates, Plato and Aristotle, in India Mahavira and Gautama Buddha -all these people lived in this period.

Question 19.
Kings conducted big Yagas. Explain them.

Question 20.
The travel of Siddhartha outside the palace utterly changed his life. Explain.
Answer:
The real name of Buddha was Siddhartha. He was the son of Suddhodana, the head of the Sakya Tribe. Siddhartha was born in Lumbini near Kapilavastu, in 563 BC. He showed much interest in religious matters even when he was very young.

He married his relative Yasodhara early and they had a son named Rahulan. One day the chariot driver took Siddhartha to the world outside the palace. This changed his life. He saw 4 big ‘sights’ – an old man, a sick person, a dead body and a sanyasi (ascetic).

These sights upset Siddhartha. He became aware of the mortality of man. He realized that the body becomes weaker and weaker and then it dies. The ascetic he met was sick and old but the joy and peace in him surprised Siddhartha. He then decided to follow the path of the ascetic. Soon he left the palace seeking the Ultimate Truth. This incident in the life of Buddha is known as the ‘Great Renunciation’.

To seek the Ultimate Truth, Buddha tried different things. He even tried to torture his body till he«was about to die. Then he abandoned such extreme measures, and sat under a Bodhi tree, immersed in meditation. He then received Enlightenment. From then he was known as Buddha (One who is endowed with Wisdom or Enlightenment) orTathagathan (One who has gained the Truth).

  1. Buddha made his first preaching (Dharmopadesam) in Saranath. Here he spoke to five ascetics whom he knew before. This preaching is known as ‘Dharma Chakra Pravarthanam’. These five ascetics became his first disciples.
  2. The rest of his life Buddha taught about Dharma or the true way of life. He died in his 80th year, in 486 BC at Kushinagari. His mortal remains were buried in 8 different places and it is believed that in all those places Stupas were built.

Question 21.
What are the basic principles of Buddhism?
Answer:
The basis of Buddhism is Four Arya (Noble) Truths with Ashtangamarga. The 4 Noble Truths Buddha taught are:

  1. The world is a sorrowful place.
  2. Desires are the cause of sorrow.
  3. If we deny our desires, we can avoid sorrow.
  4. By following the Ashtanga Marga, you can overcome sorrow.

The ashtanga margas are: right word, right deed, right life, right efforts, right memory, right view, right decision and right meditation.

Question 22.
Explain the structural working of Buddhism. Do you think that the Buddhist Sangha worked in a democratic manner? Justify.
Answer:
The disciples of Buddha belonged to different social classes. There were kings, rich people, and householders among his disciples. There were also labourers, artisans and even slaves in the group. Inside the Sangha all were equal. Once a person becomes a Bikhshu or Bikshuni, his/her previous position did not matter.

The bhikhus and bikhshunis were required to follow the Sangha rules. All these rules are explained in ‘Viriaya Pitaka’. The rules were made in such a way that they would help people to come away from their luxurious lifestyles and live in a simple way. The Sangha followed’ a democratic way.

The internal, working of the Sangha was based on the traditions of the Ganas and Sanghas in the Mahajanapadas. Problems were solved through discussions. If there were differing views, things were settled by vote.

Question 23.
What are Chaitanyas?
Answer:
From the very early times, people used to consider some places as very holy. These places had some special features. There were some rare trees or rocks there. The places were also extremely beautiful. In them there were small kovils or shrines. These places were called Chaitanya’s. Chaitanya came from the word ‘chitha’. In fact, Chaitanya is a prayer hall.

Question 24.
Explain hagiography. What is its role in recreating history?
Answer:
Hagiography is the life history of a religious leader or a saint. To understand the Buddha statues, art historians must be familiar with Buddha’s hagiography. Usually, in a hagiography, the achievements of the saint or leader are praised. They may not be fully true. But they are important, as they give us valuable information regarding the traditions followed by disciples of certain faiths.

Biographical records show that Buddha got his Enlightenment as he was meditating under the Bodhi Tree. In many statues, Buddha is not shown at all. Sometimes he is represented as an empty seat, Stupa, wheel and such symbols.

  1. The empty seat is symbolic of Buddha’s meditation.
  2. The Stupas symbolize his final days, or death (Mahaparinirvana).
  3. The wheel is symbolic of Buddha’s first preaching at Saranath.

Question 25.
In the background of the Sanchi Stupa, describe the making style and structure of the stupas. How do stupas help in the recreation of history?
Answer:
Stupas are found in Chaitanya’s. These are mounds where part of the mortal remains of Buddha or some things he used is buried. They have been made with bricks or stones. They have a lot of story value.

  1. Even before the coming of Buddhism, the practice of making stupas was in existence. Later it became attached to Buddhism.
  2. Since they are built over the remains of Buddha or the things he used, they are worshipped as a sign of Buddha and Buddhism.

HSSLive.Guru

Followers of Buddha built many stupas in different. parts of India. The Buddhist Book “Asokavadana Sishta” says that Emperor Asoka sent the mortal remains of Buddha to all the important towns of his empire and ordered stupas to be built over them. By the 2nd century BC, many stupas were built. The most famous stupas are in Bharhut, Sanchi, and Saranath. Stupa is a Sanskrit word meaning a heap or mound. In the early times, stupas were in semi-circles.

Later they were known as ‘anda’. Gradually, the structure of the stupas became complex. They now acquired circular and rectangular shapes. Over the andas, they built some kind of balcony. It was called harmika which means ‘sreekovil’. It represents the abode of god. From harmika rose a flag-post, called ‘yashti’. Around this, there were chhatris (umbrellas). Around the mound, a stone wall was constructed separating it from the material world around.

The early stupas in Sanchi and Bharhut were simple. The gates and the fences were looking as if they were made of bamboos or wood. There were four entrance arches to the stupas. These arches were decorated with sculptures. The worshippers entered the stupa from the eastern archway and went round the mound, Later these stupas were adorned with various sculptures and inscriptions. Such decorated stupas can be seen in Amaravati and Shahji-ki-dheri in Peshawar in Pakistan.

Question 26.
Explain the principles of Jainism.
Answer:

  • All things in the world have life. Even stones, rocks, and water have life and soul.
  • Non-violence is the central principle of Jainism. It taught not to trouble humans, animals, insects and plants.
  • The ultimate aim of human life is nirvana or getting moksha.
  • Nirvana is the release from birth and rebirth.
  • Karma causes birth and rebirth. If one wants to get moksha, his karma should be right. Only through the Triratnas – good knowledge, good action, and good faith-one can acquire moksha.
  • To come out of the karma circle, asceticism and meditation are essential. For that worldly life should be given up. The Jain ascetics, both men and women, should take five pledges.
    1. Don’t kill
    2. Don’t steal
    3. Don’t lie
    4. Don’t own property
    5. Practise chastity

Question 27.
Bring out the basic differences between Mahayana and Hinayana.
Answer:
Buddhism was divided into two Mahayarta and Hinayana.

1. Hinayana means lesser vehicle or lesser wheel. Hinayana followed the basic tenets of Buddhism. They followed the old tradition. They continued using Pali to propagate their faith.

2. Mahayana means Great vehicle. They followed new principles and code of conduct. Worshipping the idols of Buddha and the Bodhisatwas became an important part of this group.

3. Mahayana followers looked at Buddha as a savior and worshipped him as a god. They prayed to him for moksha and guidance. Thus piety became the main feature of Mahayana Buddhism.

4. Mahayana followers believed in the concept of Bodhisatwa. Each follower here should try to become a Bodhisatwan. By serving others and performing Doble deeds anybody can become a Bodhisatwan.

5. Mahayana followers worshipped even some famous Bodhisatwans.To propagate Buddhism, Mahayana followers used Sanskrit.

Question 28.
The Stupa in Amaravati was neglected but the one in Sanchi was protected. Why?
Answer:
Amaravati Stupa was discovered before the discovery at Sanchi. But the scholars were not then aware of the importance of preserving the historical monuments. Sanchi was discovered in 1818. Of the 4 doors, three were still intact. The 4th was lying down. The mound did not have any damage. The Europeans tried take away the doors to London or Paris, but because of the timely interference of the rulers in Bhopal, they were protected. But the ‘Mahachaitanya’ of Amaravati still remains as a small mound. It has lost all its past glory.

Question 29.
Were women allowed into the Buddhist Sangha? Clarify.
Answer:
In the beginning, only men could be members. But later women were also included. It was because of the persuasion by Ananda, who was one of the dearest disciples of Buddha, that Buddha allowed women into the Sangha. They were known as ‘bikhshunis’. The first bikhshuni was the foster mother of Buddha. Her name was Mahaprajapati Gomathy. All bikhshunis were propagators of the religion. They tried hard to become ‘theri’ – respectable women who were entitled to moksha.

Question 36.
The 6th century BC was a period of social revolutions in India. On the basis of this statement, explain the origin of Buddhism and Jainism.
Answer:
Areas to be considered:

  1. Yaga tradition
  2. Brahmin authority
  3. New Economic system
  4. Fresh questions
  5. Discussions and Talks
  6. Sacrifices and Debates

The 6th century BC was a turning point in world history. Many philosophers were found in different parts of the world. In Iran Zaratushtra, In China Confucius, in Greece Socrates, Plato and Aristotle, in India Mahavira and Gautama Buddha -all these people lived in this period.

  1. They tried to find out the mysteries of existence.
  2. They tried to find the relations between man and the universe.
  3. They tried to analyze the social and economic happenings of the time.

In India, the 6th century BC was a period of social revolution. In the Ganges valley, new Empires and cities came up. Social and economic life of the people was changing in various ways. These changes caused many religions to come up. The most important of them were Jainism and Buddhism. Let’s see the causes for their rise.

Sacrificial Tradition: Even before the coming of Jainism and Buddhism, different philosophical concepts and religious traditions were in existence. One of them was the Veda tradition. We know things about that period from Rigveda, which was collected between 1500 and 1000 BC.

Rigveda is a collection of hymns praising gods like Fire, Indra, and Soman. These hymns were recited during the sacrifices (Yagas) which were performed by the people to have health, children, cattle wealth and long life.

In the beginning, yagas were conducted in large groups for the entire people. But from 1000 to 500 BC, yagas were conducted privately by householders for the prosperity of their family or clan. But great yagas like Rajasuyam and Ashwamedhom were conducted only by kings and chiefs.

The yagas and rituals lost their earlier simplicity and purity. They became more noisy, showy, expensive and even violent. Such yagas were unaffordable by ordinary people. With the increase in the yagas and rituals, the importance and prestige of Brahmins began to increase. Things like yagas became the monopoly of Brahmins. They misused their position to exploit people.

The Problems of Jati and Language: In the post-Veda period the society was divided into 4 Varnas. It caused a lot of conflicts in the society. Brahmins claimed the highest status. They had special rights. They were exempted from taxes and punishment. The Kshatriyas objected to this. Since Mahavira and Buddha were Kshatriyas, they too were against this Brahmin domination.

Vaisyas and Sudras opposed the authority of the higher Varnas. Although the Vaisyas had money and power, their position was lower than the Brahmins and Kshatriyas. Naturally they welcomed the new religions.

All the Vedic books were written in Sanskrit. So, most of the people did not understand anything. The incantations for yagas and rituals were recited in Sanskrit. People repeated them without knowing what they said. Mahavira and Buddha propagated their religions in Pali and Prakrit. So people accepted them easily.

The New Economic System: The growth of the agricultural economy helped the new religions to develop. The use of iron made it possible to clear forests and make bigger farms. Agricultural technologies also became better. The development of agriculture increased the demand for cattle, as bullocks were used for ploughing the farms.

Brahmins killed a lot of cattle for various sacrifices and therefore there was a reduction in the cattle wealth. Priestly sacrifices of animals became an obstacle for agriculture. Naturally, people welcomed the new religions which advocated non-violence.

New Questions: The philosophical questions in the Upanishads also made people unhappy. The Upanishads say that people were interested in knowing the essence of life, the possibility of life after death, rebirth, etc. Issues like the relation of karma with rebirth caused a lot of heated debates. People were interested in finding out the Ultimate Truth.

Many people even doubted if there is anything called the Ultimate Truth. They also doubted the importance of Veda tradition. Debates and Discussions: We get some idea about the debates and discussions of those times from the Buddhist books. There were some 64 different kinds of ideological streams.

Religious teachers travelled across the country and discussed matters with the common people. They tried to impress upon the people with the importance of their thinking. People also discussed and debated these matters. These discussions were conducted in some special tents with tapering tops called ‘kudagarasala’ or in groves where the bikshus stayed during their journeys. If one philosopher defeated another one in a debate, the followers of the defeated one would follow the winning philosopher. Therefore the support for a particular stream would increase or decrease fast.

People like Mahavira and Buddha questioned the authenticity of the Vedas. They gave importance to personal actions. They asked the people, men and women, to make efforts to be free from the worries and anxieties of this world. Their attitude was quite different from the attitude of the Brahmins who gave importance to one’s birth and not his way of life.

Question 37.
Write an essay defining the principles of Buddhism, Buddha Sangha and the Spread of Buddhism.
Answer:
It is from stories that we learn about the principles of Buddhism, especially from “Suttapitaka”. Some of the stories here describe the miraculous powers of Buddha, There are also stories which speak highly of his wisdom, logic and sense of reality. These stories point out that without showing any miracles, he tried to teach people things logically.

For example there is this story. A mother whose son had died came to Buddha asking him to bring her dead son back to life. He did not perform any miracle of raising the boy from death. But he convinced the mother about the inevitability of death.

All these stories are written in Pali, the language of the common people. So, people could understand them easily. In his first preaching at Saranath we can see the important principles of Buddhism.

The world continuously changes. There is nothing permanent or immortal in it. There is no soul in it. In short the world is without eternity and without soul. The basis of Buddhism is Four Noble Truths (Arya Satyas) with Ashtangamarga. The Noble Truths are:

  1. The world is a sorrowful place.
  2. Desires are the cause of sorrow.
  3. If we deny our desires, we can avoid sorrow.
  4. By following the Ashtanga Maiga, you can overcome sorrow.

The ashtanga margas are: right word, right deed, right life, right efforts, right memory, right view, right decision and right meditation.

Followers of Buddha: For his ascetics Buddha made an organization called ‘Sangha’. Their main duty was preaching or dharmopadesa. They lived a simple life keeping only the basic necessities. They had a small bowl for taking alms. Since they lived with the alms they received they were known as ‘bikshus’. Initially there were only men. But because of the influence of Ananda, a favourite disciple of Buddha, women also were enrolled. They were called bikshunis. The first bikshuni was Buddha’s foster mother, Mahaprajapati Gomathy. All bikshunis wanted to be ‘theri’, respectable women who have got moksha.

HSSLive.Guru

The disciples of Buddha belonged to different social classes. There were kings, rich people, and householders among his disciples. There were also labourers, artisans and even slaves in the group. Inside the Sangha all were equal. Once a person becomes a Bikhshu or Bikshuni, his/her previous position did not matter.

The bikhshus and bikhshunis were required to follow the Sangha rules. All these rules are explained in ‘Vinaya Pitaka’. The rules were made in such a way that they would help people to come away from their luxurious lifestyles and live in a simple way. The Sangha followed a democratic way. The internal working of the Sangha was based on the traditions of the Ganas and Sanghas in the Mahajanapadas. Problems were solved through discussions. If there were differing views, things were settled by vote.

The Spread of Buddhism: Even during Buddha’s lifetime and also after his death Buddhism began to grow popular. It spread into China, Japan, Burma, Sri Lanka, Mangolia and Tibet. The quickly changing social environment and the dissatisfaction of people with the existing religious practices attracted them to Buddhism. The following were the additional reasons:

  1. Buddhism gave preference to values and conduct more than to birth. It rejected the caste system.
  2. It stressed compassion, especially to the children and the destitute.
  3. Its principles were easily understandable.
  4. Buddha used Pali, the language of the common people, to propagate his religion. It increased its popularity.
  5. It got the support of kings like Asoka, Kanishka, and Harsha.
  6. The working of the Buddhist Sanghas also helped in increasing its popularity.

Question 38.
What are Stupas? Prepare a note on them.
Answer:
Stupas are holy places. These are mounds where part of the mortal remains of Buddha or some things he used is buried. They have been made with bricks or stones. They have a lot of story value.

  1. Even before the coming of Buddhism, the practice of making stupas was in existence. Later it became attached to Buddhism.
  2. Since they are built over the remains of Buddha or the things he used, they are worshipped as a sign of Buddha and Buddhism.

Followers of Buddha built many stupas in different parts of India. The Buddhist Book “Asokavadana Sishta” says that Emperor Asoka sent the mortal remains of Buddha in all the important towns of his empire and ordered stupas to be built over them. By the 2nd century BC, many stupas were built. The most famous stupas are in Bharhut, Sanchi and Saranath.

Stupa is a Sanskrit word meaning a heap or mound. In the early times, stupas were in semi-circles. Later they were known as ‘anda’. Gradually, the structure of the stupas became complex. They now acquired circular and rectangular shapes. Over the andas, they built some kind of balcony. It was called harmika which means ‘sreekovil’. It represents the abode of god. From harmika rose a flag-post, called ‘yashti’. Around this there were chhatris (umbrellas). Around the mound, a stone wall was constructed separating it from the material world around. The early stupas in Sanchi and Bharhut were simple.

The gates and the fences were looking as if they were made of bamboos or wood. There were four entrance arches to the stupas. These arches were decorated with sculptures. The worshippers entered the stupa from the eastern archway and went round the mound, Later these stupas were adorned with various sculptures and inscriptions. Such decorated stupas can be seen in Amaravati and Shahji-ki-dheri in Peshawar in Pakistan.

Judiciary Questions and Answers

Question 1.
What is judiciary? Why do we need an independent judiciary?
Answer:
The Judiciary in a nation makes sure that there is law and order in the nation and justice prevails there. Although it is considered the 3rd branch of the government, it has equal importance with the other two. The yardstick of a nation’s competence is its judiciary. The Constitution of India has made the Judiciary a free Institution. Judiciary protects the rights of the citizens and it is the guardian of the Constitution.

The laws enacted by the Legislatures are interpreted by the Judiciary. By interpreting the laws, the Judiciary brings in new laws. It is the Judiciary that decides if the laws are vague or anti-Constitutional. It is the duty of the Judiciary to ensure rule of law in the country.

Question 2.
What do you mean by the independence of judiciary?
Answer:
By the independence of judiciary we mean the following:
a) The Executive and the Legislature should not interfere in the affairs of the judiciary. The judiciary is independent of the Executive and the Legislature.
b) The decisions of the Judiciary are not to be interfered with.
c) The Judiciary needs independence to pronounce judgments impartially, without fear or favor.
d) Judges should have an atmosphere in which they can deliver impartial judgments.
By independence of judiciary what is meant is not irresponsible or unilateral actions on the part of the Judiciary. Independent Judiciary is part of the democratic structure of the nation. Democratic values are to be protected. Therefore Judiciary should be loyal to the Constitution, to the democratic traditions and the people.
How can the independence of the Judiciary be ensured and maintained?
The independence of the Judiciary can be ensured and maintained by the following means:

  • Mode of appointment
  • Fixed period of tenure of office
  • Financially independent
  • Freedom from personal criticism
  • Separation of the Executive and the Judiciary
  • Handsome salary for the Judges
  • Job Security

Question 3.
Who appoints the Supreme Court Judges?
Answer:
It is the President that appoints the Supreme Court and High Court Judges. After consulting the Chief Justice, the President appoints the other judges of the Supreme Court.

Question 4.
Removal of the Supreme and High Court Judges is a very difficult task. Why?
Answer:
The removal of the Supreme and High Court Judges is done through impeachment. Supreme Court Judges can continue in office until the age of 65. Any judge can resign by giving a letter to the President. The President has the authority to remove Judges on the basis of proven corruption of incompetence. But this can be done only if 2/3 majority of both the Houses with full membership passes a resolution to such an effect and requests the President for the removal of the Judge. Supreme Court Judges get allowances and free accommodation, apart from their salaries.

It is from the Consolidated Fund of India the Judges are given their salaries. The salary and other benefits of a Judge can’t be altered in a way that adversely affects him. The decisions and activities of the Judges done in their official capacity are not subject to any criticism. The Supreme Court has its own secretariat. It is the Chief Justice that appoints officials for the Secretariat. All this is done to keep the Judiciary as an independent and impartial organization.

The case of one High Court can be moved to another High Court. Can have control and supervision over the lower courts. Lower Courts Handle civil and criminal cases.

Question 8.
The Supreme Court is the highest Court in India. In that respect, evaluate the powers of the Supreme Court.
Answer:
Original Jurisdiction: In the following cases the Supreme Court has original jurisdiction.

  • Conflicts between the Centre and one or more States.
  • In conflicts where the Centre and a State or States are on one side and a State or States on the opposite side.
  • Conflicts between States.
  • In issues connected with the election of the President and Vice President.
  • To implement Fundamental Rights as per Article 32.

Appellate Jurisdiction: The Supreme Court is the highest Appellate Court in India. Its Appellate Jurisdiction can be divided into 3 – Constitutional, Civil and Criminal.

Constitutional Cases: If the High Court testifies that the problem has some serious element of interpreting the Constitution, appeal can be given to the Supreme Court. Even if the High Court refuses to certify such a thing, if the Supreme Court feels that the case has some serious element of interpreting the Constitution, the SC can issue Special Leave of Appeal.

The Supreme Court can, on its own initiative, or on the request of the Attorney General, can ask the High Courts to move matters of public interest to the SC.

Civil Cases: If the high Court that testifies to the effect that the matter needs the decision of the SC, the case can be transferred to the SC.

Criminal Cases: In the following circumstances appeals against High Court Judgements can be made in the SC:
If an accused is left unpunished, a person or organization can file an appeal if it is felt that leaving the accused unpunished will cause some difficulty to the public. Here the Court is approached for protecting public interest. Since the Court is approached for public interest, such cases are called ‘Public Interest litigation’. Such cases usually come up in situation where there is a lack of drinking water, problems of the poor, pollution, etc. Today this has become the most energetic weapon in the hands of the Judiciary.

Public Interest Litigation:
a) Anybody who is interested in public interest, to defend the rights of others; to solve public problems, can approach the Court.
b) Since litigation is very costly in India, for defending people’s rights, this helps. In the Constitution, is stated that only the persons whose fundamental rights are violated can approach the court. But this condition has been made loose by the Supreme Court by letting Public Interest Litigation. Through this anybody can approach the court to defend the fundamental rights of others.

Question 9.
Name the Chief justice of India.
Answer:
Justice T.S. Thakur.

Question 10.
Binu: Judicial activism has highly influenced our political system.
Meena: But it has led to conflict between the Executive and the Judiciary.
On the basis of this conversation, explain the merits and demerits of judicial activism.
Answer:
Judicial activism has caused some bitter feuds and confrontations among the Executive, Legislature and Judiciary in India. When the Executive and legislature become weak, the Judiciary openly intervenes for the protection of the rights of the people. It is good for democracy but it has its weaknesses. Here are the merits and demerits of judicial activism.
Merits

  • Through public interest litigation, the powers of the Courts increased and the people’s faith in them also increased.
  • Judicial activism helped to reduce expenses for litigation.
  • Judicial activism forced the Executive to carry out its responsibilities.

Demerits

  • Increased workload for the Courts.
  • It caused open clash between the Executive and Judiciary.

Question 11.

Answer:
A High Court Judge can’t be transferred to another High Court.

Question 15.
Prepare a note on Judiciary and Parliament.
Answer:
According to the principle of decentralization of powers, each component of the government has to carry out separate functions. Judiciary has the responsibility of looking at the laws passed by the Parliament and see if they are in keeping with the Constitutional principles. In the modern times, through judicial activism, Judiciary is interfering with the Legislature. But the Parliament has the power to impeach the Judges if they found incompetent or corrupt. In fact, for the Constitution to function smoothly, cooperation between these two organs is essential.

Question 16.

b) Writ authority 32nd section (Article 32)
c) Chief Justice of the SC T.S. Thakur
d) Fundamental Rights Constitutional Court
e) Judicial Activism 1979

Question 18.
How can the independence of the Judiciary be protected?
Answer:
The Constitution has made provisions for keeping the Judiciary independent and impartial. They are as follows:
a) Mode of Appointment of Judges: The Constitution has made provisions to make the appointment of Judges above politics. The Legislature does not have much role in the appointment of Judges. For a person to be appointed as a Judge he should have experience as an advocate. He should be well-versed in law. A person’s politics does not have any role in his appointment as a Judge.
b) Fixed Tenure: The fixed tenure ensures that the Judges can work independently as they can’t be easily removed from their posts. Only in very rare circumstances can a judge be removed. This stability in the job makes them fearless and act judiciously without fear or favor.
c) Financial independence: The Judiciary does not have to depend on the Executive or the Legislature for their financial needs. The Constitution has made the salaries and allowances of the Judges beyond the jurisdiction of the Legislature. It makes the Judiciary independent. Handsome salaries and allowances will help the Judges to be independent and they will be free from the temptation of accepting bribes or such financial benefits.
d) Freedom from personal criticism: The decisions and activities of the Judge should be from criticism. Judiciary has the power to punish people for contempt of court. It is believed that this provision will protect Judges from unjust criticism. Even the Parliament can’t discuss the behavior of a Judge except as part of his impeachment process. The Judiciary can thus take impartial decisions without being afraid of criticism.
e) Separating the Executive from the Judiciary: This is another way of protecting the freedom of the Judiciary. If his fundamental rights are violated, any person can approach the SC for redress. In the form of Writ, the SC can issue special orders. For defending Fundamental Rights, the SC can issue Habeas Corpus, Mandamus, Prohibition, Quo Warranto and Certiorari. Through these Writs, the Judiciary can give orders to the Executive to take action.

Question 8.
Explain the growth in plantation crops in Kerala during the colonial period.
Answer:
An important change that happened during the colonial period in the economic system of Kerala is the growth in plantation crops. Europeans took the initiative to start new plantations and invest capital in them. The main plantations crops were tea, coffee, rubber, and cardamom. Plantations crops proved more successful in Travancore than in Malabar. There were some reasons for that. The soil and high land of Travancore were better than those of Malabar. Therefore plantations crops developed fast in Travancore. This helped the British to earn a lot of wealth. The tax collection system in Malabar was not good enough.

Question 9.
Point out the role played by missionaries in the modernization of Kerala and in its education.
Answer:
An important driving force behind the growth of Kerala Was its education. The contributions made by missionaries in this field are highly valuable. They played a big role in expanding education. In the first decade of the 19th century, the London Mission Society (LMS) and Church Mission Society (CMS) started working in Travancore.

Rev. Mead was a missionary of CMS, who devoted his entire life in expanding education here. In 1817 the CMS College and a seminary were founded at Kottayam. To encourage women’s education, the missionaries established a grammar school and other schools.

The first school in Kochi was established in 1818 in Mattanchery. A missionary named Rev. Dowson was its founder.

At the same time, Rev Twinkle Tab, a Spanish Missionary in the Salvation Army founded English schools in the southern parts, including Nagercoil.

It was Basil Evangelical Mission (BEM) that spread education in Malabar. In 1848, they established a primary school in Kallai and in 1856, another school at Thalassery.

The contributions made by the Christian missionaries encouraged the governments of Kerala to take up education more seriously. In 1817, the ruler of Travancore, Gauri Parvati Bai, started free, compulsory primary education. In many areas of Travancore, schools were established. In 1839, during the reign of Swathi Thirunal, the first English school was begun. Another school was started in Thalassery.

Question 12.
What made Pazhassiraja fight against the British? Write about the various stages of the Pazhassi Revolt.
Answer:
The Pazhassi Revolt was one of the most significant revolts in South India against the British. The British had established their authority over Malabar. Their wrong attitude to justice caused the Revolt. Keralavarma Pazhassiraja was a member of the Kottayam Dynasty of Malabar. In the beginning, he was in friendly terms with the British. In the Mysore wars, he even helped them. As a reward for his help, the British granted him the right to collect taxes from people.

But when Malabar came under their authority, the British forgot this promise. The right to collect taxes was given to an uncle of Pazhassi, the King of Kurumbanad. This King charged the people heavy taxes and used very cruel methods to get the money from them. It was in this context that Pazhassi rebelled against the British.

There were two stages in the Pazhassi Revolt. The 1st stage is from 1793 to 1797. Pazhassi started his revolt by preventing the tax collection for the British. Pazhasi’s army consisted of Muslim and Nair farmers and members of Kurichi tribe. It strongly withstood the attacks by the Company’s army. Pazhassi ‘ requested the help of Mysore to drive away the British from Wayanad. The British army was continuously defeated and in 1797, it withdrew from Wayanad, making an agreement with Pazhassi. With this, the first stage ended. The 2nd stage of the Revolt started in 1800.

The reason was the move of the British to take over Wayanad. With the help of the Kurichis and Kurumbars in his army, Pazhassi withstood the attacks. Finally, Wellesley defeated Pazhassi in a bitter battle. Pazhassi still continued his resistance. But an army under Thomas Harvey Bebar, a sub-collector of Thalassery, defeated Pazhassi on 30 November 1805, In the battle, Pazhassi lost his life.

Question 13.
There were strong uprisings against the British in Travancore and Kochi. In the context of this statement, describe the anti-colonial activities of Veluthampi Dalava and Paliathacchan.
Answer:
After occupying Malabar, the attention of the British turned to Kochi and Travancore. They tried to establish their political and commercial interests in these places. In 1800, the Company appointed Col. Macaulay as the Resident of Travancore and Kochi. Macaulay started controlling the internal affairs of these native states. By this, the rulers lost their sovereignty.

Veluthampi was the chief minister (Dalawa) of Travancore. In 1805, the British signed a friendship treaty with Travancore. Through this, the Resident got the power to interfere in the internal affairs of the state, which lost its political freedom. He insisted that the tribute which the state owed to the Company should be paid within a certain time, without giving any consideration to the financial difficulties facing the state. One man named Mathu Tharakan owed a lot of money to the state as tax arrears. Velu Thampi Dalawa ordered to confiscate his property. But Macaulay interfered and canceled the order of the Dalawa. All these incidents prompted the Dalawa to embark on an armed conflict against the Company.

Paliathacchan was the Prime Minister of Kochi. He had enmity with Macaulay. Veluthampi Dalawa made a secret agreement with Paliathacchan. They also secretly contacted the French in Mauritius and the Zamorin of Kozhikode and requested them to give their support in their fight against the Company. In 1808 the combined armies of Travancore and Kochi attacked the residence of Macaulay in Kochi. The Resident escaped in a British ship.

As the revolt was in progress the Dalawa reached Kundara. He issued a proclamation on 11 January 1809 asking the people to join him against the British. This is called ‘Kundara Proclamation’ (Kundara Vilambaram). It is considered as an important document showing the fight of South India against colonization.

The British hit back. They attacked Kochi. Paliathacchan withdrew from the revolt by signing a treaty with the British. The British persuaded the Travancore King to remove Velu Thampi from his post. Unnini Thampi became the new Dalawa. The new Dalawa asked the police, to arrest Velu Thampi. A reward was declared for catching him. Velu Thampi took refuge in a house at Mannadi. When the combined forces of the British and Travancore surrounded the house, Velu Thampi committed suicide. He did not want to be caught alive and insulted. With this, the heroic resistance against the British ended in Travancore.

Question 14.
Kerala witnessed a silent but comprehensive social revolution in the 19th and 20th centuries. Evaluate the Social Reformation Movements in Kerala in the context of this statement.
Answer:
In the 19th century, in Kerala, there were many religious superstitions, rituals, and conventions. There were also social injustices and economic injustices.
The Feudal lords suppressed the farmers. The Upper Castes ill-treated the lower castes. This made the life of poor people miserable. There were so many illogical and even foolish practices related to menstruation, marriage, pregnancy, and death. Slavery also existed here.

  • The Kerala Brahmins received a lot of privileges.
  • The lower caste people did not have a good position
    in society. The Upper Caste people controlled their modes of dress, freedom to travel and entry into temples.
  • There were untouchability and pollution rules. In Travancore and Kochi, government jobs were not given to people of lower classes.

It is in this social background that the Social Reformers started their fight against the ills of society. Although all-India Movements like Arya Samajam and Theosophical Society had their branches in Kerala, their influence was very little here. Here the social revolution was the result of local Movements. Here are some Social Reformists that worked in Kerala in the 19th and 20th centuries.

Vaikunda Swamikal: He was bom in 1808, in the . village called Sastamkotta Vila near Kanyakumari. He started Samatwa Samajam’.

He published: ‘AkilattirattuAmmanai’and ‘Arul Nool’.

Reforms:

  • For the first time, he started ‘Kannadi Prathishta’ in South India.
  • His faith was called the way of the father (“Ayyavazhi”).
  • He objected to all kinds of discrimination and stood for social equality.

Question 16.
Describe the fight for a democratic society in Kerala and how the Shanar Agitation (Channar Lahala), Vaikom Satyagraha and Guruvayur Satyagraha helped in that fight.
Answer:
There were many social evils in Kerala. There was control based on taste. Even basic human rights were denied to some castes. Human dignity did not mean anything to the Upper Classes. Against such injustice, some popular movements worked hard. Here are some of the most important movements.

Shanar Agitation: This was one of the early fights against social injustice. This took place in Southern Travancore. This is also called ‘Melmundu samara’. Women of the Channar Community were not allowed to cover the upper part of their bodies with any doth or dress. Then, when Col. Monroe was the Diwan, he issued an order allowing the Channar women (Nadar) to wear a dress if they became Christians.
The Channar women were not satisfied with this. They started appearing in the public wearing shawls like women of the Upper Classes. The Upper-Class Hindus did not like it. They attacked the Channar women, who retaliated. Finally on 26 July 1859, the government issued a royal edict removing restrictions on the dressing.

Vaikom Satyagraha: This is the first famous public protest against untouchability. This protest was organized forgetting the right to use the paths near the. Vaikom Temple by lower caste Hindus. The leaders of this Satyagraha were T.K. Madhavan, Mannath Padmanabhan, C.V. Kunjuraman, K. Kelappan, and K.P. Kesava Menon.

An important event connected with the Vaikom Satyagraha is a procession of High Caste Hindus organized by Mannath Padmanabhan. The Procession wenttoTrivandum and met Maharani Sethulaxmi Bai and presented their request to her.

The Vaikom Satyagraha and the Savama Procession (Jatha) helped in forming positive public opinion regarding Temple Entry to all Castes. Finally, Gandhi interfered and the protest was successfully concluded. All the paths, except two, around the Vaikom Temple, were opened for use by all kinds of people.

Guruvayur Satyagraha: This was a milestone in the social reform movement of Kerala. It was a great event against untouchability. This protest was begun with the demand that all Hindus should be allowed to worship in the temple. The Guruvayur temple was under the control of the Kozhikode Zamorin and only Upper Caste Hindus could worship there.

The Satyagraha started on 1 November 1931. K. Kelappan and Mannath Padmanabhan led the protest. Kelappan started a fast unto death in front of the temple.

Some fanatic Upper-Class Hindus attacked volunteers like A.K. Gopalan and P. Krishna Pillai. On 2 October 1932, on the advice of Gandhi, the Satyagraha was ended. An opinion poll was conducted in Ponnani Taluk to find out public opinion about the issue. Most of the people supported temple entry by lower caste Hindus also. Although results did not come immediately, the Satyagraha helped in forming public opinion in favour of Temple Entry by all manners of Hindus.

Question 17.
Agitation against untouchability continued in Kerala even after independence. Explain with examples.
Answer:
Agitation against untouchability had to continue in ‘ Kerala even after independence. Paliyam Satyagraha ‘ was one such agitation:
In Kochi, there were many temples in front of the houses of the Upper Caste Hindus. Lower Caste Hindus were denied entry there. Paliathacchan was the Prime Minister of Kochi. His, house was in Chennamangalam. Lower Caste Hindus tried to walk on the road in front of his house and this; brought about big clashes. It was in these circumstances the Paliam Satyagraha was started. This was done jointly by the organizations like State Praja Mandalam, Communist Party, and S.N.D.P. Yogam.

They started to agitate in front of the Paliam Family to get the street open for all. On 4 December 1947, C. Kesavan inaugurated the Satyagraha. The government used force to suppress the agitation. One of the leaders of the agitation, A.G. Velayudhan, was killed and the Satyagraha was suspended for some time, in March 1948. In April 1948, the government issued orders regarding Temple Entry for all. With this, all could use the public streets.

Question 18.
Discuss the formation of Malayali Being and the United (Aikya) Kerala Movement.
Answer:
The Malayalam language played a big role in the cultural unity of people from Travancore, Kochi, and Malabar. The roots of the Malayan Being based on language and region could be traced to “Leelathilakam”, a grammar book of the 14th century. It talks about a community that speaks Malayalam.

In fact, the concept of ‘Malayali Being’ (Individuality or Personality) was formed at the end of the 19th ‘ century. The spread of modern education was the reason for that. It gave the idea of a region where people spoke the same language.

The Printing technology and the founding of local language newspapers also helped in this concept. There was a practice of appointing outsiders to do the work in Government offices of Kerala. In 1891, a mass petition (memorandum) signed by 10,028 persons was submitted against this practice. It was called the Malayali Memorial. This was a sign of new awareness.

The National Movement gained momentum at the beginning of the 20ttl century. The concept of Malayali Being also grew with this. This concept spread beyond the boundaries of native states of Travancore, Kochi and Malabar and the need for a unified region was felt, In 1921, Kerala Pradesh Congress Committee (KPCC) was formed on the basis of language. It represented people from Travancore, Kochi, and Malabar.

The all-Kerala political meeting under Congress was summoned at Ottappalam in 1921. It was the first meeting in which representatives from Travancore, Kochi, and Malabar jointly participated. The desire for the Malayali Being was expressed in the book titled “Onnekal Kodi Malayalikal” by EMS Namboodiripad.

In April 1947, there was a United Kerala Meeting at Thrissur under the chairmanship of K. Kelappan. It passed a resolution demanding a United Kerala. On 1 July 1949, the State called “Thiru-Kochi” was formed combining Travancore and Kochi. It was an important step for the formation of United Kerala. The dream of a State of Kerala was fulfilled by the State Re-Organizing Committee under Sayed Fasal Ali. It recommended the formation of Kerala State uniting Travancore, Kochi, and Malabar. On 1 November 1956, Kerala State officially came into being.

The Root:
Root system:
In dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which bears lateral roots that are secondary, tertiary, etc.
Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 1
1. Tap root system:
The radical elongate and forms primary root or tap root that bears number of lateral roots. It is found in dicot root. eg: the mustard plant.

2. Fibrous root system:
In monocotyledonous plants, the primary root is short lived from there thin fibre roots originates. eg: wheat plant.

3. Adventitious roots:
In grass, Monstera and the banyan tree, roots arise from parts of the plant other than the radicle.

Regions of the Root:
1. Region of Root cap:
It is the covering of root apex that protects the tender apex.

2. Region of Meristem:
This is the region just behind the the root cap that is capable of active cell division.

3. Region of elongation:
The cells proximal to this region undergo rapid elongation and enlargement for the growth

4. Region of maturation:
This is proximal to the region of elongation gradually differentiate and mature

5. Region root hairs:
From the region of maturation root hairs arise. These root hairs absorb water and minerals from the soil.

4. Photosynthesis:
Some stems are lattened (Opuntia), or fleshy cylindrical (Euphorbia) structures. They contain chlorophyll and carry out photosynthesis.

5. Vegetative propagation:

  • In grass and strawberry, etc. stem spread to new niches and when older parts die new plants are formed.
  • In mint and jasmine lateral branch arises from the base of the main axis and after growing aerially and arch downwards to touch the ground.
  • In Pistia and Eichhornia the lateral branch with short internodes and each node bearing a rosette of leaves and a tuft of roots
  • In banana, pineapple and Chrysanthemum, the lateral branches originate from the basal underground portion of the main stem, grow horizontally beneath the soil and then come out obliquely upward giving rise to leafy shoots.

The Leaf:
Salient features:

  1. It is the flattened structure develops at the node and bears a bud in its axil.
  2. The axillary bud later develops into a branch.
  3. They are the most important vegetative organs for photosynthesis.
  4. some plants leaf base bear two lateral stipules.
  5. In monocotyledons, the leaf base expands into a sheath covering the stem.
  6. In some leguminous plants the leaf base become swollen, which is called the pulvinus.
  7. The lamina or the leaf blade is the green expanded part of the leaf with veins and veinlets.
  8. The middle prominent vein, which is known as the midrib.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 7

Function of veins:
Veins act as channels of transport for water, minerals and food materials.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

Venation:
1. Reticulate Venation:
The arrangement of veins and the veinlets in the lamina of leaf. Veinlets repeatedly branched to form a network. eg: dicotyledonous plants.

2. Parallel Venation:
When the veins run parallel to each other within a lamina. eg: monocotyledons plants.

Can you see the bud in the axil of leaflet of compound leaf?
A bud is not present in the axil of leaflets of the compound leaf.

Two types of compound leaves:

  1. Pinnately compound leaf: Number of leaflets are present on a common axis, the rachis, which represents the midrib of the leaf eg neem.
  2. Palmately compound leaf: In this leaflets are attached at the tip of petiole, eg silk cotton.

The Inflorescence:
The arrangement of flowers on the floral axis is termed as inflorescence. Two major types of inflorescences are

  1. Racemose
  2. Cymose.

How will you differentiate recemose inflorescence from cymose?
In racemose type, the main axis continues to grow, the flowers are arranged in an acropetal succession. In cymose type, the main axis terminates in a flower. The flowers arranged in a basipetal order.
Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 12

The Flower:
The flower is the reproductive unit in the angiosperms. It consists of different kinds of whorls (calyx, corolla, androecium and Gynoecium) arranged successively on the swollen end of the stalk or pedicel, called thalamus or receptacle.

What are the accessory and reproductive organs?
Calyx and corolla are accessory organs,while androecium and gynoecium are reproductive organs.

Did you see single accessory organ of a flower:
In lily plant, the calyx and corolla are not distinct, it is called as perianth. This is the single accessory organ of a flower. When a flower has both androecium and gynoecium, it is bisexual. A flower having either only stamens or only carpels is unisexual.
1. Actinomorphic Flower:
A flower can be divided into two equal radial halves in any radial plane passing through the centre, eg: mustard, datura, chilli.

MORPHOLOGY OF FLOWERING PLANT

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

2. Zyqomorphic:
A flower can be divided into two similar halves only in one particular vertical plane, eg: pea, gulmohur, bean, Cassia.

3. Asymmetric (irregular):
A flower cannot be divided into two similar halves by any vertical plane passing through the centre, as in canna. Afloweristrimerous, tetramerous or pentamerous when the floral appendages are in multiple of 3, 4 or 5, respectively.

Bracteate and ebracteate flower:
Flowers with reduced leaf found at the base of the pedicel, are called bracteate and those without bracts, ebracteate.

Classification of flower:
It is based on the position of calyx, corolla and androecium in respect of the ovary on thalamus
1. Hypogynous flower:
The position of gynoecium is highest when compared to other. The ovary in such flowers is said to be superior, eg: mustard, china rose and brinjal.

2. Perigynous flower:
The position of gynoecium is situated in the centre and other parts of the flower are located on the rim of the thalamus almost at the same level. The position of ovary is half inferior, eg: plum, rose, peach.

3. Epigynous flowers:
The margin of thalamus grows upward and other parts of flower arise above the ovary. The position of ovary is inferior. eg: guava and cucumber, and the ray florets of sunflower.

Parts of a Flower:
Each flower has four floral whorls -calyx, corolla, androecium and gynoecium.
Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 14

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

Calyx:
Act as protective whorl:
The calyx is the outermost whorl of the flower and segments are called sepals. The sepals are green, leaf like and protect the flower in the bud stage. The calyx may be gamosepalous (sepals united) or polysepalous (sepals free).

Corolla:
Act as an attractive whorl:
Petals are brightly coloured that attract insects for pollination. Corolla may be free (polypetalous) or united (gamopetalous).

Aestivation:
The mode of arrangement of sepals or petals in floral bud is known as aestivation. The main types of aestivation are:

  1. Valvate
  2. Twisted
  3. Imbricate
  4. Vexillary.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 15

  1. In valvate sepals or petals in a whorl just touch one another at the margin, without overlapping, Eg -Calotropis
  2. In twisted the one margin of the appendage overlaps the next one and so on. g. china rose, lady’s finger and cotton
  3. In imbricate the margins of sepals or petals overlap one another but not in any particular direction. eg: Cassia and gulmohur

Can vou find out aestivation type in papillionaceous corolla?
There are five petals, the largest (standard) overlaps the two lateral petals (wings) which in turn overlap the two smallest anterior petals (keel). This is vexillary aestivation; Eg pea and bean flowers.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

Androecium:
Structure of stamen:
Androecium is composed of stamens. Stamen is the male reproductive organ consists of a filament and an anther. Each anther is usually bilobed and each lobe has two chambers, the pollen-sacs. The pollen grains are produced in pollen-sacs. A sterile stamen is called staminode.

Differentiate between epibetalous and epiphvllous condition:
When stamens are attached to the petals, they are epipetalous as in brinjal, or epiphyllous when attached to the perianth as in the flowers of lily.

Free and fused nature of stamens:
The stamens in a flower remain free called as polyandrous. If the stamens are united into one bundle called as monoadelphous. eg: china rose, or two bundles called as diadelphous eg: pea, or into more than two bundles called as polyadelphous eg: citrus.

Variation in the length of filaments:
eg: Salvia and mustard.

Gynoecium:
Structure of carpel/pistil:
Gynoecium is the female reproductive part of the flower and is made up of one or more carpels. Acarpel consists of three parts namely stigma, style and ovary. Ovary is the enlarged basal part, on which lies the elongated tube, the style.

The style connects the ovary to the stigma. The stigma is the receptive surface for pollen grains. Each ovary bears one or more ovules attached to a flattened, cushion-like placenta.
Plus One Botany Notes Chapter 3 Morphology of Flowering Plants 16

Free and fused nature of carpel:
If carpels are free they are called apocarpous, eg lotus and rose. If carpels are fused they are called syncarpous. eg: mustard and tomato.

What happens to ovule and ovary after fertilization?
After fertilisation, the ovules develop Into seeds and the ovary matures into a fruit.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

Placentation:
The arrangement of ovules within the ovary is known as placentation. Different types of placentation are marginal, axile, parietal, basal, central and free central.

Marginal placentation: the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge eg- pea.
Axile placentation: When the placenta is axial and the ovules are attached to it in a multilocular ovary eg china rose, tomato and lemon.
Parietal placentation: Ovary is one-chambered and the ovules develop on the inner wall of the ovary e.g., mustard and Argemone.
Free central placentation: When the ovules are borne on central axis and septa are absent Eg Dianthus and Primrose
Basal placentation: The placenta develops at the base of ovary and a single ovule is attached to it eg sunflower, marigold

The Fruit:
It is a ripened ovary developed after fertilisation.
Parthenocarpic fruit:
If a fruit is formed without fertilisation of the ovary, it is called a parthenocarpic fruit. The fruit consists of a wall called pericarp and seeds.

Meaning of Drupe:
Fruit that develops from monocarpellary superior ovaries and are one seeded. Eg:- mango and coconut.

Different layers of pericarp:
In mango the pericarp is well differentiated into an outer thin epicarp, a middle fleshy edible mesocarp and an inner stony hard endocarp. In coconut fruit is drupe, the mesocarp is fibrous.

The Seed:
Seed consists of a seed coat and an embryo. The embryo is made up of a radicle, an embryonal axis, one cotyledons as in wheat, maize or two cotyledons as in gram and pea.

Plus One Botany Notes Chapter 3 Morphology of Flowering Plants

Structure of a Dicotyledonous Seed:
The seed coat has two layers, the outer testa and the inner tegmen. The hilum is a scar on the seed coat .Above the hilum is a small pore called the micropyle. It consists of an embryonal axis and two cotyledons. The cotyledons are fleshy and contains reserve food materials. At the two ends of the embryonal axis are present the radicle and the plumule.

What is non endospermic seed?
In plants such as bean, gram and pea, the endosperm is not present in mature seeds and such seeds are called non endospermous.

Structure of Monocotyledonous Seed:
Monocotyledonous seeds are endospermic but it is non-endospermic in orchids. The seed coat is membranous and fused with the fruit wall. The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer The embryo is situated in one end of the endosperm.

It consists of Vy one large and shield shaped cotyledon known as scutellum and a short axis with a plumule and a radicle. The plumule is enclosed in sheaths called coleoptile and radicle are enclosed in sheaths called as coleorhiza.

Find the equation of the line passing through the point (2, 2) and cutting off intercepts on the axis whose sum is 9.
Answer:
Let equation of the line is \(\frac{x}{a}+\frac{y}{b}\) = 1 ______(1)
Given a + b = 9
Since (1) passes through (2, 2) we have;
\(\frac{2}{b}+\frac{2}{b}\) = 1 ⇒ 2a + 2b – ab ⇒ 2 (a + b) = ab
⇒ 18 = ab. Then the numbers are 3 and 6.
Hence the equation of the line is

Question 5.
Find the transformed equation of the straight line 2x – 3y + 5 = 0, when the origin is shifted to the point (3, -1) after translation of axes.
Answer:
Let coordinates of a point P changes from (x, y) to (X, Y) in new coordinate axes whose origin has the coordinates h = 3, k = -1. Therefore, we can write the transformation formulae as x = X + 3 and y = y – 1.

Substituting, these values in the given equation of the straight line, we get 2(X + 3) – 3 (Y – 1) + 5 = 0 or 2X – 3Y + 14 = 0. Therefore, the equation of the straight line in new system is 2x – 3y + 14 = 0.

The new equation is
(X + 1)2 + (X + 1)(Y + 1) – 3(Y + 1)2 – (Y + 1) + 2 = 0
X2 + XY – 3Y2 + 3X – 6Y + 1 = 0
Therefore, the equation of the straight line in new system is x2 + xy – 3y2 + 3x – 6y + 1 = 0.

Find the equation of the line parallel to the line 3x – 4y + 2 = Oand passing through the point (-2, 3).
Answer:
The equation of the line parallel to the line 3x – 4y + 2 = 0 is of the form 3x – 4y + k = 0.
Since it passes through (-2, 3), we have;
3(-2) – 4(3) + k = 0 ⇒ -6 – 12 + k = 0

Since x-intercept is 3, the line passes through the point (3, 0). So we have;
7(3) + 0 + k = 0 ⇒ 21 + 0 + k = 0 ⇒ k = -21
Therefore the equation is 7x + y – 21 = 0.

  1. State how temperature and pH influences enzyme activity.
  2. Does the substrate concentration influence enzyme activity. If so, how?

Answer:
1. Each enzyme shows its highest activity at a particular temperature. This is called optimum temperature. Low temperature or high temperature reduces the enzyme activity. Same as, there is an optimum pH for enzyme activity. Deviation from this pH reduces the enzyme activity.

2. With the increase in substrate concentration, the velocity of the enzymatic reaction increase at first, as the substrate concentration continues to increase, the increase in the rate of reaction begins to slow down and finally no further rise in velocity occurs. This is because there is no free enzyme molecule to bind additional substrate molecule.

Question 1.
Proteins have primary structure. If you are given a method to know which amino acid is at either of the two termini (ends) of a protein, can you connect this information to purity or homogeneity of a protein?
Answer:
In there is one type of amino acid at both termini then it is homopolymer and it cannot be a pure protein. When there are different types of amino acids on both termini then it is a pure protein as proteins are heteropolymer. This property of protein in because of presence of 21 types of amino acids.

  2. Other Uses: Chicken cubes are used in making soups and dishes.

Question 3.
Explain the composition of triglyceride.
Answer:
Triglycerides are formed from a single molecule of glycerol, combined with three fatty acids on each of the OH groups, and make up most of fats digested by humans. Easter bonds from between each fatty acid and the glycerol molecule.
General structure of a triglyceride Chemical formula:

RCOO-CH2CH(-OOCR)CH2-OOCR,
where R, R’, and R” are longer alkyl chains. The three fatty acids RCOOH, RCOOH and RCOOH can be all different, all the same, or only two the same. Chain lengths of the fatty acids in naturally occurring triglycerides can be of varying lengths, but 16, 18 and 20 carbons are the most common.

Natural fatty acids found in plants and animals are typically composed only of even numbers of carbon atoms due to the way they are biosynthesized from acetyl CoA. Bacteria, however, possess the ability to synthesise odd – and branched – chain fatty acids. Consequently, ruminant animal fat contains odd num¬bered fatty acids, such as 15, due to the action of bacteria in the rumen.

Kerala Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

Cell cycle:
It involves

  1. Cell division
  2. DNA replication
  3. Cell growth

these all process take place in a coordinated way. The replicated chromosomes (DNA) are then distributed to daughter nuclei.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

Phases of Cell Cycle:
Time taken for division:
The duration of cell cycle vary from organism to organism and also from cell type to cell type

  • In typical eukaryotic cell cycle (human cells in culture) cells divide once in every 24 hours
  • Yeast cell divide in every 90 minutes.

The cell cycle and two basic phases:

  • Interphase
  • M Phase (Mitosis phase)

Interphase:
The interphase lasts more than 95% of the duration of cell cycle. It is divided into three phases.
1. G1 phase (Gap 1):
G phase is the interval between mitosis and initiation of DNA replication. In this phase cell is metabolically active and continuously grows.

2. S phase (Synthesis):
It is the period which DNA synthesis or replication takes place.

What happens to DNA after S phase?
During S phase amount of DNA per cell doubles. If the initial amount of DNA is denoted as 2C then it Increases to 4C. But the chromosome number is not changed

Events in nucleus and cytoplasm:
In animal cells, during the S phase, DNA replication begins nucleus, and the centriole duplicates in the cytoplasm.

3. G2 phase (Gap 2):
During the G2 phase, proteins are synthesised in preparation for mitosis while cell growth continues.
Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division 1

M Phase (Mitosis phase):

  • M Phase represents actual cell division or mitosis
  • The M Phase starts with the nuclear division and the separation of daughter chromosomes (karyokinesis).
  • It ends with division of cytoplasm (cytokinesis).

Quiescent stage (Go)L
Some cells in the adult animals do not exhibit division (e.g, heart cells), exit G1 phase to enter an inactive stage called quiescent stage.

Common features:
Cells in this stage remain metabolically active but no longer proliferate .But proliferate depending on the requirement of the organism.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

M Phase:
This is the most dramatic period of the cell cycle.
Mitosis is an eauational division why?
The number of chromosomes in the parent and progeny cells is the same hence* it is also called as equational division. Mitosis is divided into the following four stages:

  1. Prophase
  2. Metaphase
  3. Anaphase
  4. Telophase

1. Prophase:
It starts after cthe completion of G2 phase.
Key features:

  • Chromosomal material condenses to form compact mitotic chromosomes. It consists of two chromatids attached together at the centromere.
  • Initiation of the assembly of mitotic spindle fibres.
  • At the end of prophase golgi complexes, endoplasmic reticulum, nucleolus and the nuclear envelope disappears.
  • The centriole begins to move towards opposite poles of the cell.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division 2

2. Metaphase:
The plane of alignment of the chromosomes at metaphase is referred to as the metaphase plate.
Maximum condensation of chromosome:
In this stage, condensation of chromosomes is completed and morphology of chromosomes can be easily studied. key features:

  • Spindle fibres attach to kinetochores of chromosomes.
  • Chromosomes are moved to spindle equator and get aligned along metaphase plate through spindle fibres to both poles.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division 3

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

3. Anaphase:
key features:

  • Centromeres split and daughter chromatids separate.
  • Chromatids move to opposite poles and centromere of each chromosome is towards the pole.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division 4

4. Telophase
It is the final stage of mitosis, in which the chromosomes reached their respective poles
key features:

  • Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. Chromosome decondense as chromatin material.
  • Nuclear envelope assembles around the chromosome clusters.
  • Nucleolus, golgi complex and ER reappears.

Cytokinesis:
In this two daughter cells separate by a process called cytokinesis.
Cytokinesis in animal cell:
In an animal cell, the appearance of a furrow in the plasma membrane which gradually deepens and ultimately joins in the centre, dividing the cell cytoplasm into two.

Cytokinesis in plant cell:
In plant cells, wall formation starts in the centre of the cell and grows outward to meet the lateral walls. The formation of the new cell wall begins with the formation of a simple precursor, called the cell-plate that represents the middle lamella between the walls of two adjacent cells.

How does a cell become multinucleated?
In some organisms karyokinesis is not followed by cytokinesis as a result of which multinucleate condition arises leading to the formation of syncytium (eg: liquid endosperm in coconut).

Significance of Mitosis:
Mitosis is restricted to the diploid cells only. But in some lower plants and in some social insects haploid cells also divide by mitosis.

  1. Mitosis results in the production of diploid daughter cells with identical genetic constitution.
  2. The growth of multicellular organisms is due to mitosis.
  3. Cell growth results in disturbing the ratio between the nucleus and the cytoplasm.
  4. Mitosis helps to cell repair, i.e cells of the upper layer of the epidermis, cells of the lining of the gut, and blood cells are being constantly replaced.
  5. Mitotic divisions in the meristematic tissues – the apical and the lateral cambium, result in a continuous growth of plants throughout their life.

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

Meiosis:
The cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called meiosis.

What is common to sexually reproducing organisms?
Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas fertilisation restores the diploid phase.

Key features:

  1. Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication.
  2. Meiosis I is initiated after the parental chromosomes have replicated to produce identical sister chromatids at the S phase.
  3. Meiosis involves pairing of homologous chromosomes and recombination between them.
  4. Four haploid cells are formed at the end of meiosis II.
Meiosis I Meiosis II
Prophase I Prophase II
Metaphase I Metaphase II
Anaphase I Anaphase II
Telophasel I Telophasel II

Meiosis I:
Prophase I:
Prophase is typically longer and more complex when compared to prophase of mitosis. It is subdivided into five phases based on chromosomal behaviour i.e., Leptotene, Zygotene, Pachytene, Diploteneand Diakinesis.

1. Leptotene stage:
The chromosomes become gradually visible under the light microscope. The compaction of chromosomes continues throughout leptotene.
2. Zygotene stage:
During this stage homologous chromosomes start pairing together and this process is called synapsis. Synapsis is accompanied by the formation of complex structure called synaptonemal complex. Synapsed homologous chromosome is called a bivalent or a tetrad. The first two stages of prophase I are relatively short-lived.
3. Pachytene stage:
During this stage bivalent chromosomes appears as tetrads. This stage is characterised by the appearance of recombination nodules, the sites at which crossing over (exchange of genetic material between two homologous Chromosomes) occurs between non-sister chromatids. The enzyme involved is called recombinase.
4. Diplotene stage:
During this stage dissolution of the synaptonemal complex and the tendency chromosomes of the bivalents to separate from each other except at the sites of crossovers. These X-shaped structures, are called chiasmata. In oocytes of some vertebrates, diplotene stage last for months or years
5. Diakinesis stage:
During this stage terminalisation of chiasmata occurs. The chromosomes are fully condensed and the meiotic spindle is assembled for separation of chromosomes. By the end of diakinesis, the nucleolus and the nuclear envelope disappears.

Cell Cycle

Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division

Metaphase I:
The bivalent chromosomes align on the equatorial plate. The spindle fibers attach to the pair of homologous chromosomes.

Anaphase I:
The homologous chromosomes separate, while sister chromatids remain associated at their centromeres.

Telophase I:
The nuclear membrane and nucleolus reappear. After cytokinesis diad of cells are formed. The stage between the two meiotic divisions is called interkinesis. It is short lived. Interkinesis is followed by prophase II, a much simpler prophase than prophase I.
Plus One Botany Notes Chapter 6 Cell Cycle and Cell Division 6

Meiosis II:
Meiosis II resembles a normal mitosis

Prophase II:
Meiosis II begins after cytokinesis, The nuclear membrane disappears by the end of prophase II. The chromosomes again become compact.

Metaphase II:
At this stage the chromosomes align at the equator and Spindle fibers get attached to the kinetochores of sister chromatids.

Anaphase II:
It begins with splitting of the centromere of each chromosome allowing them to move toward opposite poles of the cell.

Telophase II:
Meiosis ends with telophase II, in which the two groups of chromosomes get enclosed by a nuclear envelope; cytokinesis follows resulting in the formation of tetrad of cells i.e., four haploid daughter cells.

Significance of meiosis:

1. Meiosis conserves the specific chromosome number of each species across generations in sexually reproducing organisms.
2. It results in reduction of chromosome number by half.

Kerala Plus One History Chapter Wise Questions and Answers Chapter 11 Paths to Modernization

Question 1.
There are physical differences between China & Japan. Explain.
Answer:
China was under Japanese and Western domination for long. The people of China began to react to these changes. They wanted to reconcile themselves with the modern world and recover their lost glory. For that, they had to free themselves from Japanese and Western control. Their two main aims were removing the gross inequalities in the country and rebuilding the nation. They realized that this could be achieved only through a revolution.

In the 1949 civil war, the Chinese Communist Party became victorious. But by the end of the 1970s, the leaders there realized that the principles of the Communist Party were actually going against the economic growth and development of the country. Following this, radical changes were brought in the economic sphere. This brought back capitalism and a free market. But at the same time, the Party retained its political control.

Japan grew into an industrially developed country. But its efforts to establish an empire led to WW II and its defeat. After the War, the control of Japan was taken over by the US. This caused the beginning of the formation of a democratic system in Japan. Japan rebuilt its economy. In the 1970s Japan became a strong economic power.

The Japanese path to modernization was made by capitalist ideologies. Modernization of Japan happened in a world where Western colonialism is dominant. The fast development of Japan underscored the power of tradition in Japanese Institutions and society. At the same time, it showed the capacity of the Japanese to understand things and the strength of their nationalism.

Question 2.
China and Japan have a long tradition of historiography. Evaluate.
Answer:
China and Japan definitely have a long tradition of historiography. For their rulers, history was a great guide. They had made departments to preserve documents and to write the royal history. The greatest historian of ancient China was Sima Quian (145 – 90 BC). Japan also had given great importance to history. This was because of the influence of Chinese culture.

Question 3.
Naito Konan is a famous Japanese scholar on China. Describe his contributions.
Answer:
Naito Konan is a famous Japanese scholar on China. His books have influenced scholars all over the world. He developed a tradition using new methods of scientific historiography to study about China. He helped the authorities to establish a Department of Oriental Studies at Kyoto University in 1907.

Naito argued that The Republican Government of Sun Yat-sen showed a way to end the dominance of the aristocracy and centralised power that were in existence in China right from the time of the Sung dynasty. He showed that there are powers in Chinese history to modernise and democratise China. He thought that Japan has a special role to play in China. He somehow lessened the power of Chinese nationality.

Question 4.
In Japan the political system was feudal. Evaluate this statement.
Answer:
In Japan the political system was feudal. The country was divided into 250 sectors. The administration of s each sector was entrusted to a Daikyo who were a group of feudal lords. Over the Daikyo there were Shoguns. Edo (the modem Tokyo) was the capital. The shoguns often asked the Daikyo to spend time in the capital. This was to prevent any threat from them. The shoguns also controlled important cities and mines. The Samurai were a set of warriors and they were the elite in the administration. They assisted the Shoguns and, Daikyos.

Japan was more or less isolated from other, countries. Japan was the only country . that escaped colonization by Europeans. There was only one Western country that had trade relations with Japan and that was Holland. The US had always Wanted the Japanese ports to open for foreign trade.

In 1853, under Matthew Perry, a powerful navy was sent to Japan by the USA. The aims of the US were getting permission for trade and establishing diplomatic relations with Japan. Japan is on the way to the sea-route to China. Therefore the US saw Japan as a good strategic point and market. They also thought of Japan as a place where their ships could refill their fuel tanks.

Matthew Perry returned to Japan the next year also. The government was forced to open two ports for the US ships and do some trade in a controlled manner. The arrival of Matthew Perry caused big movements 1 in Japanese politics. It resulted in the end of the Shogun rule and the restoration of Emperor Meiji. There was a strong protest against the Shoguns that succumbed to the foreign powers. The protesters wanted the restoration of Meiji rule. With this, the image of the emperor, who was until then a nominal figure, increased.

in 1868 there was an open revolt against the Shoguns. The revolutionaries drove away the Shogun from Edo and brought the emperor there, Edo was renamed Tokyo (Capital of the East) and was declared as the capital of the nation.

The new emperor took the title Meiji or Enlightened and became the official ruler of the country. This revolution of 1868 was known as the Meiji Restoration. The officials and people of Japan were aware of the fact that Europeans were building their colonial empires in India and other places. They also knew about the defeat of China by Britain. They were afraid if Japan also would become a colony of foreign powers.

The scholars and leaders wanted to learn about the ideas of Europeans unlike the Chinese who simply rejected them. One section of the people thought that they should learn the technology of the West but keep them away from the country. There was also an opinion that Japan should slowly open its gates to the external world.

A slogan that summed up the ideals of the Meiji Era was Fukoku Kyohei, meaning Enriching the Country and Strengthening the Army or Rich Country and Strong Army. It became the principle that led to the modernization and transformation of Japan. Japan resized that a strong economy and a strong army were needed to resist the foreigners. They saw how India yielded to the foreigners in the absence of these two things. For realizing these aims there was the need to make the people loyal citizens and build a strong sense of unity based on nationalism.

The administrative system of Japan was reorganized. The new government tried to formulate a system called the Emperor System. It was a system that followed the European model. They sent officials to Europe to study it thoroughly and then only they implemented it.

It was a system that gave the Emperor a divine aura. The emperor was considered a direct descended of the sun-god and therefore he deserved maximum reverence. He was also depicted as the leader bringing in Europeanization. His birthday was declared a national holiday. The emperor wore the military uniform of the Europeans. All edicts and orders to establish new institutions were sent out in his name.

In its education system it followed the European model, in the 1870s, stress was laid on the studies of Japanese history so that students could develop loyalty to their nation. The Educational Ministry strictly controlled the curriculum. If chose the textbooks and gave training to teachers. Education also stressed developing a moral culture in the students. The children were asked to respect and show loyalty to their nation and become good citizens.

To unify the country, the Meiji administration brought a new administrative system. The old boundaries of villages were changed. Each administrative unit had to run schools and give health facilities to its people. It also worked as an agency for the recruitment of soldiers to the army, Everyone who had passed 20 years of age had to do compulsory military service for a fixed minimum period. Japan organized a strong army. It brought a legal system that controlled the formation of political parties and meetings and did the censorship. The army and bureaucracy were under the direct control of the emperor. All these activities of the government faced stiff opposition from the public.

The new democratic constitution and the modern army were not ideologically compatible. The army started demanding a more aggressive foreign policy to conquer new regions. This led to wars with both Russia and China and in both the wars Japan came out victorious.

The demand of people for greater democracy was against the aggressive policy of the government. Japan developed economically and built an empire, suppressing democracy at home.

Question 6.
The industrialization of Japan created environmental problems. Do you agree with this statement? Clarify with examples.
Answer:
With industrialization, the factories became bigger and more numerous. In 1909, there were 1000 factories in which more than 100 people each worked. In 1920, this figure grew to 2000 factories with each one having more than 4000 workers. In spite of all that there were some 550,000 small workshops there with less than 5 workers each.

The uncontrolled and fast growth of factories, the need for natural resources like timber, etc. caused environmental damage. Tanaka Shozo, who was elected to the first House of Representatives, started the first protest against industrial pollution in 1897. This protest in which 800 villagers took part forced the government to take steps against environmental pollution.

Question 7.
What were the reasons behind the growth of the Japanese army and its aggressive nationalism?
Answer:
The Commander-in-Chief of the army was the emperor. But from 1890, it was interpreted that the army and the navy had independent control. In 1899, the, prime Minister issued an order specifying that only serving Generals and Admirals could become ministers. This increased the power of the army. The army propagated the fear that Japan is always under threat from the Western powers and it increased its strength. The same technique was used to increase its territory. They also used it to suppress the protest of the people against higher taxes and for the expansion of the army.

Question 8.
One section of the people in Japan supported Westernization but another section held fast to traditions: Discuss these paradoxical views.
Answer:
Scholars had different views about the relations Japan should have with other countries. Some scholars wanted to have cordial relations with the USA and other Western nations which were culturally on top of the world. The Meiji intellectual Fukuzawa Yukichi was highly pro-American. He was of the opinion that using its specialties Japan should become part of the Western nations.

But the next generation was not willing to accept this view of Fukuzawa. They questioned the idea of accepting Western ideas blindly. They gave stress to nationalism based on traditional values. Miyake Setsiirei, a famous Japanese philosopher, wanted Japan to develop its competence for the betterment of world culture. He said that dedicating oneself to the nation is dedicating himself to the whole world.

Another group of intellectuals was attracted by the liberalism of the West. They wanted Japan not to just concentrate oh militarism but on liberalism. Ueki Emori was the leader of the democratic movement in Japan. He wanted the establishment of a democratic government in Japan. He was an admirer of the principles of Liberty, Equality, and Fraternity, popularised by the French Revolution and he had -the view that students should be given a liberal education for their proper development. He said that liberty is more important than law and order. Another group wanted women to be given voting rights. All these pressures forced to government to declare a new Constitution.

Question 9.
The transformation of Japan into modernity was reflected in the life of the people. Explain.
Answer:
The transformation of Japan into modernity definitely was reflected in the life of the people. It brought great changes in family relations. Japan had a patriarchal joint family system. Under the elder of the family, many generations lived under the same roof. But when Japan became modern, the old system collapsed and nuclear families replaced the old system. In the nuclear family, the husband earned the livelihood and the wife managed the household affairs.

This change in the system brought changes in the family possessions, family entertainment and even the structure of the house. Construction companies made cheap houses and gave them to people on installment.

Question 10.
After their defeat in WW II, Japan resurrected as a global economic power. Evaluate this statement.
Answer:
The quick rebuilding of the economy that Japan achieved after their defeat in the WW II is called the Post-War Wonder or the Post-War Miracle. The roots of that success can be seen in the long history of Japan.

Japan had a tradition of democratic protests and intellectual and creative activities. Moreover, the social solidarity that was there even before the War became stronger after the War. It helped in the cooperation and collective efforts of government, bureaucracy, and industry. The demands for many things created by the Korean and Vietnam Wars also helped in boosting the Japanese economy.

The Tokyo Olympics of 1964 was the start of a new era in Japanese history. The high-speed bullet trains that began in 1964 showed the world the competence of Japanese technology. The ability of the Japanese to produce high quality but cheap products by using top technology surprised the world.

Question 11.
When was a Republican Government established in China? Who is the founder of modem China?
Answer:
In 1911, overthrowing the Manchu dynasty, a Republic was established in China under Sun Yat-sen. He is the founder of modem China.

Question 12.
For the reconstruction of the country, Sun Yat-sen prepared a scheme. What was that?
Answer:
Sun Yat-sen was worried about China’s fate. For the reconstruction of the country, he prepared a scheme. This is called “Three Principles” or San-Min Doctrine or Tridemism. The three principles are nationalism, democracy, and socialism.

Nationalism meant driving away the Manchus and other imperialists. Democracy meant establishing a democratic government. Socialism meant controlling capital and bringing equality in land ownership.

Question 13.
What is the reason for the origin of the May 4 Movement? What were its goals?
Answer:
The Republican Revolution of 1911 did not bring any basic change in the society. When the WW I started, China joined the Allied Powers, but Britain did not return the regions it had captured earlier. Naturally, there was a serious protest against the decisions of the Paris Conference. Gradually it became a Movement. This Movement started on 4 May 1919 in Beijing and it was known as May 4 Movement.

This Movement severely attacked tradition calling to save the country through modem science, nationalism, and democracy. It demanded the sending away of foreigners, removing inequalities and reducing poverty. Their other demands were: Use simple language for writing, stop the custom of foot-binding, end the slavery of women, bring equality in marriage and bring economic development to end poverty.

Question 14.
The Kuomintang government was a failure. Do you agree with this statement? Justify your answer.
Answer:
After the republican revolution, the country entered an era of crises. The Kuomintang (National People’s Party) tried to unify the nation and bring stability and the Chinese Communist Party became the most powerful one.The base of the political vision of Kuomintang was the ideas of Sun Yat-sen. They put forward 4 great principles: clothes, food, shelter, and travel.

After the death of Sun Yat-sen, Chiang Kai-shek became the leader of Kuomintang. In 1928, a national government was formed by Kuomintang. Chiang Kai- shek was the President of the government. Kuomintang government was a failure. The causes for its failure were its narrow social base and narrow political vision. The Party ignored the farmers. It did not take into account the increasing social inequalities. The Chiang government could not carry out Socialism, which was the main principle of Sun Yat-sen’s scheme for China. The Chiang government tried to impose a military order and suppress protests instead of solving popular problems.

Question 15.
Prepare a seminar paper on the 1949 Chinese Revolution.
Areas to be considered: Background, Chinese Communist Party and Mao Zedong, Long March, Civil War.
Answer:
In 1937 Japan attacked China. Instead of resisting the Japanese attack, the Kuomintang government retreated. Long wars had weakened China. The prices of things skyrocketed and the life of common people was hard.

Rural China faced two crises:

a) Environmental crisis:
Soil fertility was lost, there was deforestation and there were floods.

b) Social and economic crisis:
Exploitative land-owning system, debt, primitive technology, very poor exchange system.

Following the Russian Revolution, in 1921 the CPC (Communist Party of China) was established. The success of the Russian Revolution had a big impact on the world. Soon the Russian leaders Lenin and Trotsky established the Comintern (Community International) or Third International. Its aim was to end exploitation and establish a world government. If supported all the Communist Parties all over the world. But they had the traditional Marxist view that only an urban labour class could bring about a revolution. Soon Comintern became a means of protecting only Soviet interests, it was disbanded in 1943.

Mao Zedong was the leader of CPC. In the strategy of the Communist Party, Mao brought a big change. He saw the peasants as a great power. He believed that only peasants could bring about a revolution. Thus he moved away from the traditional Marxian view. The success of Mao made CPC very strong and it was helpful in bringing victory over the Kuomintang.

When the attacks from the Kuomintang became intense, Mao and his followers retreated to the Jiangxi Mountain. From 1928 to 1934 he camped here. There he formed a strong Peasant Council. By confiscating land the distributing them to people, he made the Council very strong. Mao wanted to establish an independent government and army. He was aware of the problem of women. He encouraged the formation of organizations of village women. He objected to the traditional system of marriage and brought a new marriage law. It made divorces simple.

In 1934, Mao and his followers left their camps to escape from the attacks by Kuomintang. Their destination was Yanan, 6000 miles away. This march became a historical event and is called the Long March. The Communists who reached Yanan formulated their plans. They gave importance to suppress the warlords, bring land reforms and fight against the foreign imperial powers. This helped them to make a strong social base.

In 1937 when Japan attacked China, the Communists cooperated with the Kuomintang to fight against the common enemy, Japan. But when the war ended, this cooperation ended and the civil war between Kuomintang and Communists restarted. The Communists led a final assault against the Kuomintang and captured the capital Nanjing. Chiang Kai-shek and his army escaped to Taiwan. On 1st October 1949, the new Chinese Republic under Mao was proclaimed.

Question 16.
The basis of the 1949 Chinese Democratic Republic was “New Democracy”. Explain.
Answer:
In 1949, the Chinese Republic was established. Its basis was a new democracy. This was different from the Soviet Union s concept of the dictatorship of the Proletariat. Democracy means the union of all social classes.

All the decisive areas of the economy were taken under the control of the government. Private entrepreneurship and private land owning were gradually ended. This scheme lasted until 1953, The government declared that there was going to be a socialist transformation. To make industrialization fast, Mao brought in the scheme called the Great Leap Forward, in 1958.

The government encouraged people to establish iron melting furnaces behind their homes. For collective farming, in the rural sector, communes of people were established. In 1958 itself there were 26,000 such communes.

Mao was able to make people ready for working to achieve the aims of the Party. His main goal was creating a socialist man.

A socialist man should have five livings:
love for the fatherland, love for people, hard work, science, and common property. Democratic organizations were formed for peasants, women, students and other classes of people.

Question 17.
Write a note on Mao’s “Great Cultural Revolution”.
Answer:
To defeat his critics and enemies in 1965 Mao started his scheme called the Cultural Revolution. It was a movement against the old culture and old customs and rituals. It gave more importance to ideological knowledge than professional knowledge. Instead of healthy debates, it gave prominence to slogans. He entrusted the job of making Cultural Revolution practical to the Red Guards which consisted of the army and students.

In the beginning, the CR was a failure. It weakened the Party. It ruined the economy and educational system. The entire country was in turmoil. But by the end of the 1960s, things began to change. In 1975 Deng Xiao Ping came to power and he ended the CR.

Question 18.
Critically examine the reforms made in China from 1978.
Answer:
Deng Xiao Ping brought many revolutionary reforms. Many of them were of a deviant nature from the Socialist Principles. He made Party control very strong. He brought in a Socialist market system. In 1978 the Party declared its four reformist goals, known as four modernizations. They were developments in science, industry, agriculture, and defence. He allowed debates that did not question party lines.

In the new free atmosphere, new ideas developed. On 5 December 1978, there was a wall writing declaring the fifth modernization. It declared that without democracy all other modernizations were useless. It also criticized the Communist Party for not solving the problem of poverty and for not ending sexual exploitation. But all the demands were suppressed. In 1989 more intellectuals in China demanded greater democracy. It demanded the ending of unchanging ideologies. In 1989 students protested in the Tiananmen Square in Beijing. The protests were cruelly put down by the army and many students died. This incident was condemned by the whole world.

There were debates about the development of China after the reform period. There are three distinct views.

 

  1. The first view was that through strict political control, economic liberalization and cooperation with the global market, development was possible. The Party supported this view.
  2. Many questioned the stress on the market. Critics pointed out that inequalities among social classes and regions and gender inequality would cause conflicts in the society.
  3. There was also a view that the ideas of Confucianism should be revived. They argued it was possible to build a new society by using their own traditions and without borrowing ideas from Western models.

Question 19.
Evaluate the political changes in Taiwan and discuss the possibility of its unification with China.
Answer:
Chiang Kai-shek who was defeated by China escaped to Taiwan (Formosa). He went to Taiwan with a lot of gold and priceless artifacts. In Taiwan, he formed a government in exile called Republic of China. Taiwan was once part of the Chinese Empire. In 1894-95, when China was defeated by Japan, Japan occupied this region and transformed it into their colony. When Japan lost in the WW II, Taiwan was again given back to China.

Chiang Kai-shek ruled Taiwan like a despot. His government was repressive. Chiang denied the people freedom of speech and political protests. He also kept the local people away from the administration. But through land reforms, he was able to increase agricultural production and to revive the economy. The economy which was based on trade grew fast and the gap between the rich and poor was reduced. The biggest change that happened in Taiwan was its step toward democracy.

This happened after the . Death of Chiang Kai-shek in 1975. In 1987 the martial law in Taiwan was repealed. Opposition political parties were allowed to function. In the first free elections, the process to bring the local people to power was started. Most countries had only trade relations with Taiwan. Since Taiwan is part of China, it is not possible to have full diplomatic relations and embassies there. The unification of Taiwan with China is a matter of dispute. However, the relations between Taiwan and China are improving. Taiwan has large investments and trade with China.

Question 20.
Japan and China chose different paths for their modernization. Discuss.
Answer:
Both China and Japan are industrialized but they chose separate paths for their modernization. Japan was successful in maintaining its freedom and in using its traditional expertise and styles in new ways. But the elite class who were responsible for the modernization process made the people develop an aggressive nationalism. It helped in the continued rule by an administration that often suppressed the demands for democracy and social changes.

Although it developed internally, it embarked on an imperial policy. The modernization process of Japan was influenced by Western powers. Even as the Japanese followed Western models they also practised their own ideas. All this affected Japan’s nationalism. Japan wanted to free Asia from Western domination. This was the justification they gave for their own imperial designs.

In the 19th and 20th centuries, China changed a lot. It tried to deny tradition and look for new ways to build national unity and strength. The Chinese Communist Party and its followers tried to end traditions which kept the people in poverty, made women slaves and kept the country underdeveloped. They made a slogan that meant power to people and it raised people’s hope. But the repressive regime often spoilt the beauty of the slogans of liberty and equality. However, it was able to end centuries-old inequalities and to spread education among people and make people aware or the need for change.

Question 14.
What is demography?
Answer:
Demography is the scientific study of populations. This word comes from Greek. ‘Demos’ means people. ‘Graphein’ means to write or describe. By combining these two words we get demography. It means describing people. It studies the trends and processes that affect populations.

Question 15.
What is the difference between formal demography and social demography?
Answer:
Formal demography is mainly concerned with measurements. It is concerned with things like birth, death, emigration, marriage, divorce, etc. Social demography stresses the social, economic and political aspects of the population.

The main function of formal demography is measuring and analyzing the components of population change. It stresses evolutionary analysis. For this, it uses mathematical and statistical methods. It is a method that helps in foreseeing changes in population growth and its structure.

Social demography or population studies study the reasons for changes in population and its structures and their results (repercussions). Social demographers believe that demographic processes are controlled by social processes and structures. People like social scientists, demographers also try to find out the social causes for demographic tendencies.

Question 16.
What are the two processes that helped in the growth of demography?
Answer:
pThe two processes are the formation of national states and the growth of statistical science. With the advent of the modern age, national states came up in Europe as important political organizations. With this, the role and responsibility of the modern nations began to increase. For example, administering public health, economic policies related to manufacturing and industry, tax, its collection, increasing incomes, urban management – all these needed the attention of the nation.

The growth of numerical (statistical) science was also important. As the areas of activity of nations increased, there was a need to have precise statistical data. Statistical data were needed in the case of population and economic systems with regard to their number, size and measure.

Question 17.
Who were the people that came out with demographic theories?
Answer:
Different theories about demography have been proposed by different scholars. The theories of Malthus, the Liberals, Marx and Kingsley David have been extensively discussed.

Question 18.
Explain the demographic theory of Malthus.
Answer:
One of the most popular theories on demography is that of Thomas Robert Malthus. He was an economist from England. In 1798 he published a book titled “An Essay on the Principle of Population”. In this book, he explained his demographic theory. His theory is pessimistic. Here are the important ideas – of his theory.

Malthus argued that population is increasing on a much faster rate than the increase in the means of livelihood (food, clothes, agricultural products etc). He pointed out that there is tremendous growth in population but there is no proportional growth in food production. Therefore mankind id destined to live in permanent poverty. The increase in population always exceeds the increase in agricultural production.
Population increases geometrically (in the order 2, 4, 8, 16.. 32, 64, 128, etc.). But food production increase is only arithmetical or parallel.
Plus Two Sociology Chapter Wise Questions and Answers Chapter 2 The Demographic Structure of Indian Society 1
In short, increase in population will always keep food production behind. So Malthus tried to show that mankind will be faced with serious food shortages and ultimate ruin.

Malthus argued that the only way to make progress is by controlling population growth. He said there were two ways of controlling it One is moral restraints like marrying late, celibacy etc. The other is natural controls which inside wars, famine and diseases. Unfortunately, the power of mankind to limit population growth by moral control is very limited. Therefore Malthus believed that only natural controls will help in limiting population growth. He explained that natural controls are Nature’s way of solving the problem created by the geometrical growth of population and the arithmetical growth of good production.
Plus Two Sociology Chapter Wise Questions and Answers Chapter 2 The Demographic Structure of Indian Society 2
The Theory of Malthus remained influential for long. ’ But theoreticians who showed that economic growth will be greater than population growth proved Malthus wrong. The experiences of European countries showed that the theory of Malthus is not right By the 2nd half of the 19th century there were changes in. the population growth. By the beginning of the 20th century, these changes were quite dramatic.

Birth rate reduced drastically. (The reason for this is the use of various means of birth control.) Contagious diseases were checked. (This was helped by progress in medical science.) There was tremendous increase in food production. (Improved technologies helped this.)

Although there was considerable increase in population, food production increased and the living standards became better. Thus the predictions of Malthus were proved wrong.

The theory of Malthus that the increase in population caused poverty was severely criticised by the Liberals and Marx. They argued that poverty and hunger are not the results of population growth, but the result of inequitable distribution of wealth and other resources. They showed that in an unjust society, the few wealthy live in great luxury whereas the majority of people live in, poverty.

Question 20.
Explain the theory of Demographic Transition.
Answer:
Demographic Transition is another important theory in demography. This theory was presented in the 1940s by the American Social Scientist Kingsley Davis. His theory was an optimistic one. This theory argued that population growth is related to all-round economic development. He showed that each community or society follows its own development model in accordance with its population growth. The Theory of Demographic Transition says there are three basic stages in population growth.

In the first stage the society is not developed and the economic condition is backward. At this stage, both birth rate and death rate will be high. Therefore the growth in population will be small.

In the 2nd stage iff a transition stage. There is technological growth in the society and there is a big jump in the growth of population. The birth rate is high and the death rate is low. The growth in population will be very high.

The 3rd and last sage start when there is extensive industrialization. At this stage, birth rate and death rate will below.
Plus Two Sociology Chapter Wise Questions and Answers Chapter 2 The Demographic Structure of Indian Society 4
It is during the transition between the 1st and 3d stage there is high growth of population or population explosion: When disease control, public health care, and nutritious food bring down the death rate, the birth rate remains high. There is thus population, explosion. The society will take some time to get adjusted to the new situation. The nature of procreation that was in existence during the time of poverty and high death rate will take some time to get used to the new situation of technological progress and high longevity.

This kind of transition took place in Europe at the end of the 19th century and the beginning of the 20th. This kind of transition (changing the nature of procreation to suit the new circumstances) is also followed by the developing nations. These nations are trying hard to reduce the birth rate as deaths are getting reduced. The transition stage is not yet complete in India. Although death rate is drastically reduced, it has not been possible to reduce birth rate drastically.

Question 21.
What is birth rate and death rate?
Answer:
Birth rate is the number of live births per 1,000 people per year in a place (a country, a State, a district or a geographical region).
Date rate is the number of deaths per 1000 of a population perversion a place.

Question 22.
What are the common indicators affecting population?
Answer:
There are many indicators that affect population.
a. Birth rate: Birth rate is the number of live births per 1,000 people per year in a place (a country, a State, a district or a geographical region).
b. Death rate: Date rate is the number of deaths per 1000 of a population per year in a place.
c. The rate of growth in population: The growth in population is the difference between birth rate and death rate. When this becomes 0 or very low, we can say that the population is stable. In some societies, there is negative growth rate. This is when birth rate is less than the death rate in those societies.
d. Fertility rate: This is the number of live births per 1000 women between the ages of 15 and 49 years. The ages 15 to 49 show the period when women can conceive.
e. Total fertility rate: This is an imaginary rate. It represents the number of children that would be born alive to a woman if she were to live to the end of her childbearing years (5-49) and bear children in accordance with age-specific fertility rates of the specified year.
f. Child death (mortality) rate: The under-5 mortality rate is the number of children who die by the age of five, per thousand live births per year.
g. Maternal mortality rate (MMR): This is the annual number of female deaths during delivery, per thousand deliveries. The high child and maternal death rates indicate poverty and backwardness.
h. Longevity: This is complex concept related to population. It shows the number of years an average person will live.
i. Gender Ratio: It shows how many females are there for thousand males in a region.
j. The Age Structure of the Population: It shows the number of persons in various age groups in proportion to the total population.
k. Dependency Ratio: Many persons cant-do any work either because they are children or they are too old. They have to depend on others. The dependency ratio is a measure showing the number of dependents (aged 0-14 and over the age of 65) to the total population (aged 15-64).

Question 23.
What are the common concepts and indicators of population?
Answer:
The common concepts and indicators of population are:

  • Birthrate
  • Death rate
  • Growth rate
  • Fertility rate
  • Total fertility rate
  • Maternal death rate
  • Longevity
  • Gender ratio
  • Age Structure of the Population
  • Dependency Ratio

Question 24.
Describe the size and growth of the Indian population
Answer:
After China, India has the largest population in the world. According to the 2011 Census, the population of India is 121 crores (1.21 billion). The growth rate in India is not always high. Between 1901 and 1951, the annual rate of growth never exceeded 1.33%. This is a moderate growth. In fact, the growth rate between 1911 and 1921 was drastically reduced to the negative growth of -0.03%. In short, the growth until 1921 was very slow. There are some reasons for it. In 1918-19 there was an epidemic which kept population under check. In the epidemic 12.5 lakh people, i.e. 5% of the total population, died. Killer diseases like plague and malaria and famine killed lakhs of people.

During the post-independent period, population growth increased considerably. In the period 1961-1981, it went up to 2.2%. After that, even though our growth rate was reduced, India still continues to be one of the most highly populated countries of the world. The , following table gives the population and the growth rate during the various census years.

Question 25.
What are the reasons for the decreased death rate. after 1921?
Answer:
There were two reasons that were responsible for the reduced rate after 1921. One is the control over famines and the other i.sthe control of epidemics. Of these two, the second one is more important. The worst killers of the past were different kinds of fever, plague, smallpox, malaria and cholera. The plague in the 1918-19 period killed 12.5 lakh people, 5% of the total population. It was known as Spanish Plague and it was a global killer. Progress in the treatment of this kind of epidemics, preventive vaccinations, improved hygiene and so on helped in the prevention of these killer diseases.

However, even now diseases like malaria, tuberculosis, dysentery, bloody diarrhoea and so on are killing people. But the death rate is not as high as before. In 1994, there was a plague in Surat. In 2006, diseases like dengue fever and chikungunya were reported from different parts of the country. There were also different kinds of bird flu in the country not long ago. Death rate was reduced because of effective control of famines. Famines caused heavy loss of life in the past. With their control deaths are reduced.

Question 26.
Explain the Age Structure of the Indian population.
Answer:
The majority of Indians are young. Thus India has a youthful population. The average age of India is less compared to many other countries. In 1971 persons below 15 were 42%. From this, in 2001, it was reduced to 34%.

The percentage persons between 15 and 60 increased from 53 to 59. People above 60 increased from 5 to 7% during the period 1971-2001.
AGE STRUCTURE: Depending on age, people are divided into children, adults and senior citizens (old people). Children 0-14; Adults 15-60; Above 60 senior citizens.

Question 27.
There are regional variations in the age structure. Clarify.
Answer:
There are wide variations in regional age structures. States like Kerala have begun to achieve an age- structure that is similar to the one in developed countries. But in Uttar Pradesh, the picture is quite different. There the ratio of young people is more and that of the old people is less. When we look at India as a whole, the age ratio is in between these two extremes, because India has States like Kerala and also like Uttar Pradesh.

Question 28.
Describe the features of gender ratio in India,
Answer:
In the structure of population, gender ratio has an important place. It shows the gender equilibrium. Gender ratio means how many women are there for 1000 males. Historically gender ratio favoured women. It means there were more women than men. But for almost a century the gender ratio shows there are more men than women.

At the start of the 19th century, the gender ratio was 972: 1000. It means 972 women for 1000 men. In the 21st century, the ratio is 933:1000.
The reduction in the number of women has been going on for the last 4 decades. This is a matter for great concern. In 1961 it was 941: 1000; in 2011, it is 940 : 1000.

Question 29.
Describe the apprehensive change in the gender ratio of children.
Answer:
A fact that shocked demographers, policymakers, social workers and even ordinary citizens is the drastic reduction in the gender ratio of children. It was from 1961 that gender ratio related to age was calculated. The ratio of children aged up to 6 is called child gender ratio. This used to be higher in the past, but unfortunately, it has been seriously decreasing. In the 1991-2001 period, the female-male ratio was 933:1000, which was the highest. It had increased by 6 points from the previous 927:1000. At the same time, child gender ratio went down to 927 from 945, showing a decrease of 18 points. Thus for the first time, the child gender ratio became lower than the common gender ratio.

The decrease in the child gender ratio in some States is cause for greater concern. In 6 States and in the Centrally Administered Regions, the child gender ratio is even lower than 90Q girls to 1000 boys. Punjab is the worst in this case. There it is 798:1000. It is the only state that is below 800 females for 1000 males. Just behind Punjab, there are Haryana, Chhatisgarh, Delhi, Gujarat and Himachal Pradesh.

In Uttaranchal, Rajasthan, Uttar Pradesh and Maharashtra, the ratio is less than 925. In Madhya Pradesh, Goa, Jammu-Kashmir, Bihar, Tamil Nadu, Karnataka and Orissa, the ratio is above the national average of 914, but it is below 950.

The best ratio is in Kerala. But even here things are not so fine, as the ratio is just 964. Mizoram has the highest ratio in India. There it is 971:1000. Demographers and social scientist point out many reasons for the decrease in the gender ratio, with less women and more men. The most important of them are reasons of health and the attitude of the society towards females.

Question 30.
What are the main reasons for the decrease in the female-male (gender) ratio in India?
Answer;
Demographers and social scientist point out many reasons for the decrease in the gender ratio, with less women and more men. The most important of them are reasons of health and the attitude of the society towards females.

Women have greater health problems than men because of conception and childbirth. In some cases, women die during delivery. The question whether this is the cause for the inequality in gender ratio has much relevance. In the past deaths during or after delivery were common. But with the progress in medical science, such deaths are reduced to a minimum. Maternal death rate has been seriously reduced because of nutritious food, education, awareness, improved medical facilities and transport and communication. So it would e difficult to support the argument that maternal deaths during delivery are a major cause for the unequal gender ratio.
The other reason is said to be the behaviour and attitude of the society to women.

In some societies, birth of females is considered a curse and a burden. In such societies, there are many female foeticides and female infanticides. During pregnancy, through scanning, it is determined whether the child is male or female. If the foetus is female, then abortion is done. This is female foeticide. Some times in some superstitious societies female children are killed (female infanticide) even after their births because of certain cultural and religious superstitions. This points to a serious social issue.

There are evidence that even now this kind of heinous acts are done in India. Using technology like sonograms (ultra-sound echo) the gender of the child is determined before birth, and if it is proved to be female, abortion is done. In all the hospitals we see notices against the determination of child sex using this technology. But unscrupulous gynaecologists take bribes and let the parents know the sex of the unborn child.

Question 31.

Question 33.
Explain the inequality in literacy fate between male and female.
Answer:
Literacy rate gets different depending on the gender, region and social communities. Female literacy rate is far below male literacy rate. According to the 2011 census, male-female gap in literacy rate is 16.7. Depending on the social communities also, there will be difference in the female literacy rate. Among the Scheduled Castes and Scheduled Tribes, female literacy rate is very low.

Regional differences also cause disparity in the female literacy rate. States like Kerala are having 100% literacy rate or are very close to it. Kerala has the best literacy rate, both male and female. But States like Bihar are far behind in literacy rate, especially that of female.

The disparities in literacy are very significant. It will create generation gap very acute. Illiterate parents may not be very keen on giving their children higher education. They may not have the circumstances for it. Naturally, then, the present inequality will continue.

Question 34.
The majority of Indians live in villages. Comment.
Answer:
It is very true that the majority of Indians live in villages. According to the 2011 census, 69% of Indians live in villages. Only 31% live in cities and towns. But the urban population is steadily increasing. At the start of the 20th century, the urban population was 11%. By the beginning of the 2181 century, it went up to 28%. Thus in one century, the urban population increased 214 times. The urban population is increasing because of the modem development plans.

Question 35.
The main reason for the increase in urban population is the migration of people from villages to urban areas (cities and towns). How did urban life become more attractive? Why do the rural population migrate to urban centres?
Answer:
Mass media and television played a big role in making rural people migrate to urban centres. The glittering lifestyle and the luxuries that consumer culture has brought in are constantly shown on television and this captivates the rural people. Today even in the remotest villages, people know how the city people live and their high living standards with all sorts of amenities and luxuries. This has tempted the villagers to try their luck in cities.

The gap between the urban and rural people is slowly getting bridged. Even in the past, villages were not inaccessible to market forces. They tried to establish and maintain trade relations with villages to sell their goods. With the growth of the media, especially the visual media, market forces and villages got closer. Now villages also have become part of the consumer culture. Villages are very active in market activities.

Villagers are tempted to move into cities and towns because of their familiarity with the glittery lifestyle available there. Media have been largely responsible for awakening this desire in the rural people.

Greater employment opportunities in towns and cities also attracted people towards them. With urbanization in top gear, the villagers were attracted to the magnetic field of the cities and towns. People who were unemployed in the, villages or those who had only very little work moved into cities and towns

Question 36.
Describe the ill effects (disadvantages) of migration
Answer:
movement of rural people into urban centres quickened the destruction of common properties like ponds, forests and grasslands. These were the sources of the means of livelihood of poor villagers. Those who did not have much land managed to exist by fishing, collecting things from forests and grazing their cattle. With the mass movement of people to urban centres, there was a change everywhere.

Construction work destroyed the grassy plains and the ponds became dry. Forests were cleared either for cultivation or for some other kind of industrialization. Villagers were forced to buy many things which they used to get free. For example, from the public ponds, they could catch fish, from forests they could get firewood and other things, and from the grasslands, they got grass for their cattle. Now nothing was free and people were forced by buy things which were free until now. Thus villagers began to suffer more. Since cash income in hard to come by in villages, their problems got multiplied.

Question 37.
What were the reasons for the migration to cities by villagers?
Answer:

  • Influence of the media, especially television.
  • Love for consumerist culture.
  • Finding better life with good amenities and luxuries.
  • Opportunity to look for jobs.
  • The unfamiliarity in the cities. Since people don’t know you much, you can do any job and get money. But in villages, one does not like to do jobs which are considered below one’s status.

Question 38.
Describe the population policy of India.
Answer:
Population policy is a very important matter in a country. It is related to the health, prosperity and development of the nation. Population and development are mutually related. For the development of a country, an energetic population is necessary. At the same time, overpopulation can do a lot of harm to development. This problem of overpopulation is felt by the developing nations. The problem of overpopulation was recognized by India at an early stage. In 1952 itself, India declared a population policy.

The population policy of the Indian Government stressed family planning. For this, a Family Planning Board and a Family Planning Department were established. Five Year Plans also gave due importance to family planning. The population policy of India was based on the National Family Planning Programme. The aims of this Programme were:

  • Control the rate of growth of the population in a way desirable to the society.
  • Encourage various birth control methods and thus reduce the growth rate.
  • Improve public health.
  • Create awareness in people about the problems of overpopulation and matters related to health.
