C4 and CAM plants have both adapted to hot, dry conditions by minimizing photorespiration. C4 plants accomplish this by using spatial separation of carbon fixation and the Calvin cycle within the leaf, while CAM plants accomplish this by using temporal separation of these processes by opening their stomata at night and storing carbon as an acid until daylight. C3 plants do not have these adaptations, and are therefore less efficient in hot, dry conditions.
