| A. Kranz anatomy |
| B.The product of photosynthesis is oxaloacetic acid |
| C. Both PEP carboxylase and Ribulose- bisphosphate carboxylase act as carboxy- lating enzymes |
A) only A and B, but not C
B) only B and C, but not A
C) only A and C, but not B
D) all A, B and C
Correct Answer: C
Solution :
\[{{C}_{4}}\] plants are characterised by Kranz type of anatomy i.e., chloroplast containing mesophyll cells and bundle sheath cells. The phosphoenol pyruvate in mesophyll cells combine with \[C{{O}_{2}}\]in presence of PEP carboxylase and forms oxalo acetic acid. The product of photosynthesis is starch.
