उत्तर
Epidermis is a layer of parenchymatous cells that forms the outermost covering of the plant body. Epidermis consists of compactly arranged cells without any intercellular spaces. On the aerial plant parts, it secretes a thick, waxy, water-resistant layer called cuticle on its outer surface. These features .make the epidermis protective against loss of water, mechanical injury, and the invasion of parasites.
