In which layer of the skin do cells undergo mitosis to replenish the loss of skin cells?

Stratum Basal
Stratum Spinosum
Subcutaneous layer
Reticular layer

The correct answer is: Stratum Basal

Cells undergo mitosis in the Stratum Basal layer of the skin. The other options are incorrect because - B: Stratum Spinosum is responsible for adding strength and flexibility to the skin, not for cell regeneration. - C: Subcutaneous layer mainly consists of fat and connective tissue, and does not experience cell division. - D: Reticular layer is primarily composed of collagen and elastin fibers, and does not contain actively dividing cells.
