pigmentkorrels
Pigmentkorrels, or pigment granules, are small particles within cells that contain pigment molecules. In animals the best characterized are melanosomes, specialized organelles inside melanocytes responsible for the synthesis, storage, and transfer of melanin, the pigment that colors skin, hair, and eyes.
Melanin production occurs inside melanosomes through the enzymatic action of tyrosinase, converting tyrosine to melanin. Melanosomes
In the eye, pigment granules are present in the retinal pigment epithelium, where melanin helps absorb stray
In plants and some algae, pigment granules occur in chromoplasts and related plastids, which accumulate carotenoids
