Zoology - Organisms and Populations Question with Solution | TestHub

Many desert plants have a thick cuticle on their leaf surfaces and have their stomata arranged in deep pits (sunken) to minimize water loss through transpiration. They also have a special photosynthetic pathway (CAM) that enables their stomata to remain closed during day time. Some desert plants likeOpuntia, have no leaves and the photosynthetic function is taken over by the flattened stems.
