HUMAN NUTRITION

Detailed explanation-1: -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.

Detailed explanation-2: -Wax occurs in almost all vascular plants as a constituent of the cuticle, although few plants have pronounced accumulations. Wax acts as a protective coating on the epidermis of leaves, stems, and fruits, reducing desiccation or abrasion, or resisting pest attack.
