C₄ plants are more efficient in photosynthesis than C₃ plants due to:

Options

(a) Higher leaf area
(b) Presence of larger number of chloroplasts in the leaf cells
(c) Presence of thin cuticle
(d) Lower rate of photorespiration

Correct Answer:

Lower rate of photorespiration

Explanation:

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.
