Detailed explanation-1: -Xerophytic plants can have less overall surface area than other plants, so reducing the area that is exposed to the air and reducing water loss by transpiration and evaporation. They can also have smaller leaves or fewer branches than other plants.
Detailed explanation-2: -Xerophytes are a group of plants that are adapted to survive in arid regions like desert and snow-covered areas. Xerophytes have stomata with microscopic openings and elongated leaves that store large amounts of water. Sometimes even their stems store water. They have deep-spreading roots that search for water.
Detailed explanation-3: -They have well developed roots. They store water in succulent water storing parenchymatous tissues. They have small sized leaves with waxy coating. Some of the xerophytes complete their life cycle within a very short period when sufficient moisture is available.
