When the rate of photosynthesis becomes equal to the rate of respiration.

Vedclass · Answer

(B) The compensation point is the specific light intensity at which the rate of photosynthesis exactly equals the rate of respiration in a plant. At this point,the amount of $CO_2$ produced during respiration is exactly consumed by photosynthesis,and the amount of $O_2$ produced during photosynthesis is exactly consumed by respiration. Consequently,there is no net exchange of gases between the plant and the atmosphere. Therefore,the correct option is $B$.
