Solution

(a) cuticle

In desert plants, the epidermis has a thick waxy coating of cutin ( a chemical substance with waterproof quality) on its outer surface helps them to reduce the rate of water loss.The cuticles of plants function as permeability barriers for water and water-soluble materials. The cuticle prevents plant surfaces from becoming wet and helps to prevent plants from drying out.
