Question

Quizplus · Accepted Answer

As cells move towards the surface of the skin, they undergo a process called apoptosis, which is programmed cell death. This is necessary for the shedding of dead skin cells and the renewal of the epidermis. The other options are not accurate; cells do not continue to divide as they move towards the surface, their nutrient supply does not significantly improve, and they do not become dermal cells.
