Explanation:
Detailed explanation-1: -Xerophytes are plants which can survive in dry or desert regions, i.e. with little water. Sunken stomata ensure less water loss, thus reduces the rate of transpiration. Hence, these are characteristically found in xerophytes.
Detailed explanation-2: -Other xerophytic adaptations include waxy leaf coatings, the ability to drop leaves during dry periods, the ability to reposition or fold leaves to reduce sunlight absorption, and the development of a dense, hairy leaf covering.
