Detailed explanation-1: -They are adapted to conserve water for adverse conditions. Step by step answer:Xerophytic plants: The morphology and physiology of xerophytes are altered to conserve water. It stores large quantities of water, particularly during dry periods.

Detailed explanation-2: -Xerophytic leaves are specifically adapted to aid in photosynthesis despite harsh, hot, and dry environmental conditions. A key adaptation for many is a waxy cuticle that coats the entire leaf, preventing water loss and stabilizing temperature.

Detailed explanation-3: -The xerophytes adaptation increases water intake and limits water loss and also stores water efficiently. The water intake adaptations include deep or widespread roots, and high salt content to increase osmosis.

Detailed explanation-4: -Xerophytes have special structural (xeromorphic) and functional modifications, including swollen water-storing stems or leaves (see succulent) and specialized leaves that may be hairy, rolled, or reduced to spines or have a thick cuticle to lower the rate of transpiration.

Detailed explanation-5: -Hairy leaves-minimise water loss by reducing air flow and creating a humid microclimate which reduces evaporation rate and the water potential gradient.
