- Describe the life cycle of epidermal cells?
Epidermal cells begin life deep in the epidermis where cells divide to form new cells. The new cells gradually mature and move upward in the epidermis as new cells form beneath them. About two weeks after they are formed, the cells die amd become part of the surface layer of the epidermis. After another two weeks, dead cells in the surface layer are shed and replaced by the dead cells below.
