Question

the layer of the epidermis that includes melanocytes and a single row of columnar cells that undergo mitosis is the: a stratum corneum b stratum spinosum c stratum basale d stratum granulosum

Explanation:

The stratum basale (also known as stratum germinativum) is the deepest layer of the epidermis. It contains melanocytes which produce melanin (the pigment that gives skin its color). It also has a single row of columnar or cuboidal cells that are capable of undergoing mitosis (cell division) to produce new keratinocytes. The stratum corneum is the outermost layer with dead, keratin - filled cells. The stratum spinosum has spin - like projections between cells and is involved in cell adhesion. The stratum granulosum has cells with keratohyalin granules as they prepare to become part of the stratum corneum.

Answer:

C. stratum basale
