Answer and Explanation:
The epidermis is the outer protective tissue. They have a waxy cuticle that covers the outer walls. The cuticle prevents excessive loss of water and protects the inner cells from mechanical injury and infection. In plants that grow in dry habitats, the cuticle is very thick and waxy to reduce water loss. The leaves are also hairy to reduce water loss. In plants that grow in wet habitat, the cuticle and epidermal cells are transparent to allow light. The cuticle is thin to increase the rate of water loss.
