Question

Cells of the epidermis contain a pigment called .............. .

Answer 1

The cells of the epidermis contain a pigment named as Melanin. This is secreted from the melanocyte cells of the epidermis.

The melanin has the capability of protecting our skin from the harmful rays of the sun. the amount of melanin is proportional to the darker skin tone.

The pigment is black in color and its precursor is a compound names, Argesterol-7-Dehydrocholesterol which is a by-product of Vitamin D.

Tanning of skin under the sun happens due to the increased synthesis of Argesterol-7-dehydrocholesterol and which ultimately results into formation of more melanin. 

Answer 2

The basal cell layer contains cells called melanocytes. Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun.
