Expert Answer
Epidermis is the outermost layer of cells covering the plant body, especially the leaves, stem and roots. A waxy layer called cuticle, often covers the epidermal surface and prevents water loss. Epidermis of leaves bear stomata for exchange of gases and transpiration. Epidermal cells of roots bear root hair that increases the surface area for water absorption.
