Q. $CO_{2}$ released in bundle sheath is used in the
A) $C_{4}$-cycle
B) $C_{3}$-cycle
C) Respiration
D) Sugar break down processes
Explanation
The $CO_{2}$ formed in the bundle sheath cells by decarboxylation of malic acid used in the Calvin cycle. In that way, $C_{4}$-plants have their own $CO_{2}$ for the Calvin cycle. That’s why $C_{4}$-plants can perform Calvin cycle even in very low $CO_{2}$ concentration
