NEET BIOLOGY

Detailed explanation-1: -In some forms of photosynthetic bacteria, a chromatophore is a pigmented(coloured), membrane-associated vesicle used to perform photosynthesis. They contain different coloured pigments. Chromatophores contain bacteriochlorophyll pigments and carotenoids.

Detailed explanation-2: -Photosynthetic bacteria have membrane bound vesicular structures on the infoldings of their cell membranes. This structure is called chromatophore. It stores the bacterial pigments such as bacteriochlorophyll.

Detailed explanation-3: -Phycocyanins and phycobilins are the pigments present in photosynthetic bacteria such as blue-green algae. These pigments are arranged on lamellar structures in concentric rings or plates. They are accessory pigments and do not participate in photosynthesis.

Detailed explanation-4: -Photosynthetic bacteria convert the water and the carbon dioxide into the oxygen and the sugar with the help of sunlight. These bacteria possess the chromatophores. The pigment containing cells is present in the chromatophores.

Detailed explanation-5: -Chromatophores that contain large amounts of yellow pteridine pigments are named xanthophores; those with mainly red/orange carotenoids are termed erythrophores.
