Detailed explanation-2: -Melanocytes produce and store a black pigment called melanin. They produce more melanin when your skin is exposed to sunlight, which is why it becomes darker. This protects the skin from the sun’s harmful UV rays. Lymphocytes and Langerhans cells play an important role in fighting germs.
