Bundles called melanosomes are formed by which type of cell?

Melanosomes are specialized organelles found within melanocytes, which are the cells responsible for the production of melanin, the pigment that gives color to the skin, hair, and eyes. When melanocytes synthesize melanin, they package these pigment molecules into melanosomes. These melanosomes then move to the skin's keratinocytes (the primary cells in the outer layer of the skin), where they transfer melanin, contributing to the pigmentation of the skin.

Understanding this function highlights the critical role melanocytes play in skin health and pigmentation, making them essential to both natural skin color and protection against UV radiation. The connection between melanocytes and melanosomes helps clarify how skin color is determined and how various hair removal techniques may interact with pigmentation.
