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.
