Question

Which of the following characteristics out of A, B and C are exhibited by $C subscript 4 end subscript$ -plants?
Kranz anatomy
The product of photosynthesis is oxaloacetic acid
Both PEP carboxylase and ribulose-bisphosphate carboxylase act as carboxylating enzymes.

(a) Only A and B, but not C
Only B and C, but not A
(c) Only A and C, but not B
(d) All A, B and C

The correct answer is: (c) Only A and C, but not B

$C subscript 4 end subscript$ -plants are characterized by Kranz type of anatomy, i.e., chloroplast containing mesophyll cells and bundle sheath cells. The phosphoenol pyruvate in mesophyll cells combine carbon dioxide in presence of PEP carboxylase and forms oxaloacetic acid. The product of photosynthesis is starch.
