Final answer:
Melanosomes are produced and released from the melanocytes of the stratum basale, which is the deepest layer of the epidermis, to be transferred to keratinocytes in the stratum spinosum.
Step-by-step explanation:
Melanosomes, which are organelles containing the pigment melanin, are produced and released from the melanocytes of the stratum basale.
The stratum basale is the deepest layer of the epidermis and contains stem cells, melanocytes, and Merkel cells. When the melanosomes are produced, they are transferred to the keratinocytes in the stratum spinosum to provide protection against UV radiation. This transfer of pigment is what gives the skin its color and provides some protection from sun damage.Melanosomes are produced and released from the melanocytes of the stratum basale, which is the deepest layer of the epidermis, to be transferred to keratinocytes in the stratum spinosum.
