$C_{3}$ - plants have (1) calvin cycle (2) kranz type of anatomy (3) photorespiration (4) No photorespiration
1 1,2 and 3 are correct
2 1 and 2 are correct
3 2 and 4 are correct
4 1 and 3 are correct
Explanation:
D $\mathrm{C}_{3}$ plants are defined as the plants that use the $\mathrm{C}_{3}$ pathway in the dark reaction of photosynthesis. There is no indication of kranz anatomy by the leaves of these plants. The plants that undergo the Calvin cycle for carbon fixation are known as $\mathrm{C}_{3}$ plants. * $\mathrm{C}_{3}$ plants do not have the anatomic structure nor the abundance of PEP carboxylase to avoid photorespiration like $\mathrm{C}_{4}$ plants. Hence, $\mathrm{C}_{3}$ plants have photorespiration. The RuBP binds with $\mathrm{O}_{2}$ instead of being converted into 2 PGA molecules to form one phosphoglycerate and phosphoglycolate molecule in a pathway called Photorespiration.

What will be the number of Calvin cycles to generate one molecule of hexose?
1 8
2 9
3 4
4 6
Explanation:
D Calvin cycle occurs in all photosynthetic plant it does not matter whether they have $\mathrm{C}_{3}$ or $\mathrm{C}_{4}$ path ways. There are 6 atoms of carbon required for the synthesis of one glucose molecule, Hence, to produce one molecule of hexose sugar, 6 turns of Calvin cycle are required.

Which one of the following contain agranal Chloroplast ?
1 $\mathrm{C}_{3}$ plants
2 Succulants
3 $\mathrm{C}_{4}$ plants
4 Hydrophytes
Explanation:
C The $\mathrm{C}_{4}$ plants contain agranal chloroplasts. Bundle sheath cell of $\mathrm{C}_{4}$ plants contain larger chloroplasts in size and arranged centripetally and also contain starch granule but lack grana. This is the reason there chloroplasts are agranal as they lack grana where as is mesophyll cells there are smaller chloroplasts with well developed grana.

In Hatch and Slack pathway
1 Chloroplast are of same type
2 Occurs in Kranz anatomy where mesophyll have small chloroplast whereas bundle sheath have granal chloroplast
3 Occurs in Kranz anatomy when mesophyll have small chloroplast where as bundle sheath have larger, agranal chloroplast
4 Kranz anatomy where mesophyll cell are diffused
Explanation:
C Hatch and Slack pathway occurs in Kranz anatomy where mesophyll have small chloroplasts whereas bundle sheath have larger agranal chloroplast. Kranz anatomy is a specialized structure in $\mathrm{C}_{4}$ plants where the mesophyll cells are clustered around the bundle-sheath cell in a ring-like fashion.

In the photosynthesis of $C_{4}$ plants the first 4 carbon compound is formed by the following reaction
1 Decarboxylation of pyruvic acid
2 Carboxylation of PEP
3 Oxidation of malic acid
4 Oxidative decarboxylation of malic acid
Explanation:
B In the photosynthesis of $\mathrm{C}_{4}$ plants, the first 4 carbon compound is formed by the carboxylation of PEP (Phosphoenolpyruvate). PEP carboxylase is an enzyme that attaches a carbon dioxide molecule to PEP, forming oxaloacetate, a 4 carbon compound. Oxaloacetate then transported to bundle sheath cells, where it is decarboxylated to release $\mathrm{CO}_{2}$ and calvin cycle.
