Q. Generally, plants adapted to dry tropical conditions have
A) $C_{2}$ pathway
B) $C_{3}$ pathway
C) $C_{5}$ pathway
D) $C_{4}$ pathway
Explanation
Plants that are adapted to dry tropical regions generally have the $C_{4}$ pathway. Though these plants have the $C_{4}$-oxaloacetic acid as the first $CO_{2}$ fixation product they use the $C_{3}$ pathway or the Calvin cycle as the main biosynthetic pathway
