chromatophore

 [kro-mat´o-for]
any pigmentary cell or color-producing plastid.

chro·mat·o·phore

(krō-mat'ō-fōr),
1. A colored plastid, due to the presence of chlorophyll or other pigments, found in certain forms of protozoa.
2. Melanophage; a pigment-bearing phagocyte found chiefly in the skin, mucous membrane, and choroid coat of the eye, and also in melanomas.
3. Synonym(s): chromophore
4. A colored plastid in plants, for example, chloroplasts, leukoplasts, etc.
[chromato- + G. phoros, bearing]

chromatophore

(krō-măt′ə-fôr′)
n.
1. Any of several types of pigment cells, especially one found in a fish, amphibian, or reptile.
2. A multicellular organ in cephalopods that contains pigment cells.
3. A specialized pigment-bearing organelle in certain photosynthetic bacteria.

chromatophore

A pigment-containing cell.

chromatophore

  1. (also called chromoplast) a pigmented PLASTID of plant cells which may be green due to the presence of chlorophyll or differently coloured because of the presence of CAROTENOID pigments. CHROMATOPHORES are often CHLOROPLASTS in which the pigment has broken down, as in the ripening of fruit.
  2. (in animals) a cell with pigment in the cytoplasm which can be dispersed or concentrated so changing the colour of the animal as a whole. Animals with this characteristic include frogs, chameleons, cephalopods.
  3. (in photosynthetic bacteria and CYANOBACTERIA) a membranous structure carrying photosynthetic pigments.
