chromatophore
- (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.
- (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.
- (in photosynthetic bacteria and CYANOBACTERIA) a membranous structure carrying photosynthetic pigments.
