Homework Statement



Cells called melancytes that lie deep in the epidermis produce a pigenment, called melanin, that gives skin color. Exposure to ultraviolet light- from sun or tanning lamp-causes melanocytes to produce more melanin, which they pass along the skin above them, yielding suntan. But, why would sun exposure prompt this increased production? What is the function of a tan, in other words?

i think a suntan acts as a protective measure. the darker the skin the better it will emit infra red radiation.

True, melanin absorbs UV radiation.
As for the tan, think what occurs when you get a tan.
Remember melanin is a pigment, it changes the color of light it reflects.
