In some forms of
photosynthetic bacteria
Photosynthesis is a process used by plants and other organisms to Energy transformation, convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemica ...
, a chromatophore is a pigmented(coloured), membrane-associated
vesicle used to perform photosynthesis. They contain different coloured pigments.
Chromatophores contain
bacteriochlorophyll pigments and carotenoids.
In
purple bacteria, such as ''
Rhodospirillum rubrum'', the light-harvesting proteins are intrinsic to the chromatophore membranes. However, in
green sulfur bacteria, they are arranged in specialised
antenna complexes called
chlorosomes.
