Question

which layer of the epidermis is a single row of stem cells attached to the dermis where most new cells are made?
stratum spinosum
stratum lucidum
stratum basale
stratum granulosum

Explanation:

The stratum basale is a single row of stem cells attached to the dermis. It is the layer where most new cells are made through cell division. The other layers (stratum spinosum, stratum lucidum, stratum granulosum) are above the stratum basale and do not have this characteristic of being the primary site for new cell production from stem - like cells attached to the dermis.

Answer:

C. Stratum basale
