Answer 16.
A-mesophyll
B – Bundle sheath cell
The primary Co₂ acceptor is a 3-carbon molecule phosphoenol pyruvate (PEP) and is present in the mesophyll cells. The enzyme responsible for this fixation is PEP carboxylase or PEPcase. It is important to register that the mesophyll cells lack Ru- BisCO enzyme. The C₄ acid OAA is formed in the mesophyll cells. It then forms other 4-carbon compounds like malic acid or aspartic acid in the mesophyll cells itself, which are transported to the bundle sheath cells. In the bundle sheath cells these C₄ acids are broken down to release Co₂ and a 3-carbon molecule. The 3-carbon molecule is transported back to the mesophyll where it is converted to PEP again, thus, completing the cycle. The Co₂ released in the bundle sheath cells enters the C₃ or the Calvin pathway, a pathway common to all plants. The bundle sheath cells are rich in an enzyme Ribulose bisphosphate carboxylase-oxygenase (RuBisCO), but lack PEPcase. Thus, the basic pathway that results in the formation of the sugars, the Calvin pathway, is common to the C₃ and C₄ plants.

Answer 17.
Phellum, phellogen and phelloderm are the three kinds of tissue.

One type of meristematic tissue called cork cambium or phellogen develops, usually in the cortex region. Phellogen is a couple of layers thick. It is made of narrow, thin-walled and nearly rectangular Cells. Phellogen cuts off cells on both sides. The outer cells differentiate into cork or phellem while the inner cells differentiate into secondary cortex or phelloderm. The cork is impervious to water due to suberin deposition in the cell wall. The cells of secondary cortex are parenchymatous. Phellogen, phellem, and phelloderm are collectively known as periderm.

Answer 9.
Glycolysis is a partial oxidation, glucose undergo oxidation to form two molecules of pyruvic acid. And this pyruvic acid undergo many type of reaction according to the organism and form the sub-stance which our body need. Pyruvic acid, in yeast like organism undergo fermentation and form Co₂ and ethanol. In animal cells it form lactic acid. Finally reach in Krebs cycle then undergo electron transport then it form ATP. Such a long cycle is needed to convert glucose to ATP. So we say that glycolysis is a partial oxidation.

Answer 10.
b. Grana.
c. Non-cyclic: When the two photosystems work in a series, first PS II and then the PS I, a process called non- cyclic photo-phosphorylation occurs. The two photo-systems are connected through an electron transport chain, as seen earlier -in the Z scheme. Both ATP and NADPH + H⁺ are synthesised by this kind of electron flow.

Cyclic: When only PS I is functional, the electron is circulated within the photosystem and the phosphorylation occurs due to cyclic flow of electrons. A possible location this could be happening is in the stroma lamellae. The excited electron does not pass on to NADP+ but is cycled back to the PS I complex through the electron transport chain. The cyclic flow hence, results only in the synthesis of ATP.

Answer 11.
a. The term anabolism means building up process. The term catabolism means break down process. Respiration involve the break down of organic molecules like glucose. But Intermediate compounds produced during the break down of glucose is used for synthesis of complex molecules like fats and proteins. Therefore respiratory pathway involve both anabolism and catabolism, hence can be considerate as amphibolic pathway.
b. The site of perception of light by a plant for a photo periodic responds is not a flower but leaves.

Answer 12.
a. Drupe.
b. A – Epicarp, B – Mesocarp
c. Parthenocarpic fruit is the fruit which formed without fertilization of the ovary. But in figure it is true fruit which formed by fertilization of monocarpellary superior ovary.
