Cuticle Layer of a Plant

Cuticle Layer of a Plant

A plant cuticle covers the epidermis of the leaf. It consists of hydrocarbon and lipid polymers that form a wax around the leaf. This layer is water proof and protects the plant from dirt and other impurities that may contaminate the plant. The cuticle layer of a plant is also involved in a plant’s water conservation system. One way in which it contributes is through the stomata imbedded in its surface. These stomata are holes that regulate water loss. In the picture above the cuticle layer covers the surface of the plant.
