The outer covering of a leaf is known as the cuticle, which is a waxy layer that helps minimize water loss and protect the leaf from environmental stresses such as pathogens and UV radiation. Beneath the cuticle is the epidermis, a layer of cells that provides additional protection and allows for gas exchange through specialized structures called stomata. Together, these layers play a crucial role in maintaining the leaf's health and functionality.
