Q. Which of the following statements regarding $C_{4}$-plants is false?
A) The primary $CO_{2}$ acceptor is a 5-carbon molecule
B) The initial carboxylation reaction occurs in Mesophyll
C) The leaves that fix $CO_{2}$ have two cell types
D) The Mesophyll cells lack Rubisco enzyme
Explanation
In $C_{4}$plants, primary $CO_{2}$acceptor is 3C-compound, phosphoenol pyruvate (PEP) and is present in the mesophyll cells. The enzyme responsible for this fixation is PEP carboxylase or PEPcase.
