Question

Quizplus · Accepted Answer

UV radiation stimulates increased production of melanin by melanosomes. Melanin is a pigment produced by melanocytes (cells in the skin) that helps protect the skin from damage caused by UV radiation. When the skin is exposed to UV radiation, it stimulates the production of melanin in the melanosomes, which leads to the darkening or tanning of the skin.
