Detailed explanation-1: -In land plants the cuticle is the outermost layer interacting with the environment. This lipophilic layer comprises the polyester cutin embedded in cuticular wax; and it forms a physical barrier to protect plants from desiccation as well as from diverse biotic and abiotic stresses.

Detailed explanation-2: -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. Epidermis cells contain no. chloroplasts – not true of the stoma cells.

Detailed explanation-3: -Leaf cuticle-Leaves are covered with a waxy cuticle which also stops their cells from becoming infected. It is a strong barrier that pathogens find it hard to pass through. This means pathogens cannot get into the tissue underneath the leaf’s waxy cuticle.

Detailed explanation-4: -A cuticle is a non-cellular waxy layer secreted by epidermal cells. It protects the epidermis and reduces water loss.

Detailed explanation-5: -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.
