Detailed explanation-1: -It is made up of cutin which is secreted by the epidermis of the leaf. A primary function of the waxy cuticle is to reduce water loss through the surface of the leaves, which is particularly important in water deficient areas like deserts which receives very little rainfall.

Detailed explanation-2: -So the leaf has another adaptation to reduce water loss: the waxy cuticle, so called because it is made out of a water-repellent substance called cutin.

Detailed explanation-3: -Cuticle – It is an epidermal layer seen in vascular plants, cells of this layer release cutin which is a waxy substance, preventing water loss from the stomata.

Detailed explanation-4: -A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface.

Detailed explanation-5: -The waxy cuticle is a thin layer atop the epidermis. Its function is to reduce the water lost from the leaf. In arid (dry) conditions this cuticle layer can be quite thick.
