Hard and waxy leaves: Many desert plants have hard and waxy leaves that help reduce water loss through evaporation. The waxy coating on the leaves, called the cuticle, acts as a barrier, preventing excessive water loss.

Tiny leaves: Some desert plants have reduced the size of their leaves or have tiny leaves to minimize the surface area exposed to the hot desert environment. This reduces water loss through transpiration.

Thorns instead of leaves: Certain desert plants, such as cacti, have modified their leaves into spines or thorns. These spines serve multiple purposes, including reducing water loss by reducing the surface area, shading the plant from excessive sunlight, and providing defense against herbivores.
