Physiological adaptations of endotherms to maintain body temperature include changes to rate , hibernation or , evaporative cooling and heat exchange . 3 transpiration dehydration cooling Xylem exchange balance The main form of water loss from plants is , which is required to move water up the and for evaporative . Water is also lost when stomata are open for gas . Plants that live in areas of low water availability must achieve a between how much water the plant can afford to lose for cooling , transpiration , exchange of gases and the risk of . 4 concentration arid woody exposure storing internal stomata Xerophytes are plants that live in conditions and have adaptations that equip them to achieve this balance and survive in their hostile environment . They do this by : reducing the of transpiring plant structures to sunlight , reducing the temperature , regulating the opening and closing of the , reducing difference in water between the plant and the outside air , water and producing fruits .
