AP BIOLOGY

Detailed explanation-1: -The xerophytes majorly have thick and swollen stems. This is to store and retain water for longer periods. The stomata are the openings of the pores present over the leaves of the plants. Gaseous exchange and evaporation occur through stomata.

Detailed explanation-2: -Plants with adaptations which allow them to live in hot and dry conditions are called xerophytic . The following adaptations allow plants to survive in the hot desert environment: Small leaves-these ensure that less water is lost from the plant by transpiration because the leaf has a smaller surface area.

Detailed explanation-3: -Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis.
