What is Epidermis?
The '''epidermis''' is the [[skin]] or surface layer of an [[animal]] or [[plant]]. At its most basic, it is a sheet of [[cell]]s. The cells are continually replaced by [[cell division]] ([[mitosis]]), and the layer (in animals) is sensitive to [[stimulus|stimuli]] such as [[touch]]. In land vertebrates the epidermis has many layers; the outer layers may be [[reinforce]]d by [[keratin]]. ==Related pages== * [[Skin]] * [[Epidermis (botany)]] * [[Epidermis (zoology)]] {{biology-stub}} [[Category:Integumentary system]]
