Explanation:
Detailed explanation-1: -Melanocyte is a highly differentiated cell that produces a pigment melanin inside melanosomes. This cell is dark and dendritic in shape. Melanin production is the basic function of melanocyte. With the process of differentiation this cell loses the proliferative potential.
Detailed explanation-2: -Melanin is made by melanocytes. Up to 8% (1 in every 5 to 10 cells) in the epidermis is a melanocyte (melano means black) make up 8% of the epidermal cells. Melanocytes make the pigment called melanin. Tyrosine is converted into dihydroxyphenylalanine (DOPA) which is then polymerised into melanin.
