The structural features (morphology) and fundamental chemical processes (physiology) of xerophytes are variously adapted to conserve water, also common to store large quantities of water, during dry periods. This enables them to maintain a humid environment around them. She's TESOL certified and a National Geographic Certified Educator. Xerophytic Plant Examples.
