WebbThe epidermis of root is used for absorption of water and minerals. It bears root hairs. Root hairs are tubular extensions of the outer walls of the epidermal cells. The root hairs bearing cells are smaller cells than other cells. A thin layer of cuticle is also present on some epidermal cells. The epidermis is the outermost cell layer of the primary plant body. In some older works the cells of the leaf epidermis have been regarded as specialized parenchyma cells, but the established modern preference has long been to classify the epidermis as dermal tissue, whereas parenchyma is classified as ground tissue.

"WebbThe epidermis is composed of thin-walled cells and is usually only one cell layer thick. The absorption of water and dissolved minerals occurs through the epidermis, a process greatly enhanced in most land plants by the presence of root hairs—slender, tubular extensions of the epidermal cell wall that are found only in the region of maturation.
