The epidermis is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment. The epidermis of most leaves shows dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions. The cells of the epidermis are structurally and functionally variable. Most plants have an epidermis that is a single cell layer thick. This helps in the protection of the plant body.
So the correct option is 'A and B'.
