Question 24
In desert plants, rate of water loss gets reduced due to the presence of

(a) cuticle
(b) stomata
(c) lignin
(d) suberin

Answer 1

(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.
