Why are C₄ plants able to photosynthesize with no apparent photorespiration? A)They do not participate in the Calvin cycle. B)They keep their stomata open most of the time in hot,dry climates,which allows for water loss to prevent photorespiration. C)They keep their stomata closed most of the time in hot,dry climates,which conserves water and oxygen to inhibit photorespiration. D)They do not use rubisco to fix CO₂. E)They exclude oxygen from their tissues.

Question

Quizplus · Accepted Answer

C₄ plants are able to photosynthesize with no apparent photorespiration because they do not use rubisco to fix CO₂, which is the enzyme responsible for photorespiration. By using an alternative pathway for carbon fixation, these plants are able to avoid the wasteful process of photorespiration.
