  1. C4 plants are more efficient in photosynthesis than C3 plants due to :
    1. Higher leaf area
    2. Presence of larger number of chloroplasts in the leaf cells
    3. Presence of thin cuticle
    4. Lower rate of photorespiration
Correct Option: D

C4 plants are more efficient in photosynthesis than C3 plants due to photorespiration. Photorespiration is an inhibitory process that decreases the rate of photosynthesis. It is absent in C4 plants and present only in C3 plants.
