The correct option is A Chromatophores In cyanobacteria (blue-green algae), bacteriochlorophyll, bacteriopheophytin or bacterioviridin pigments containing membranous extensions called chromatophores are present. Chromatophores are the sites of bacterial photosynthesis. Hence, pigment containing membranous extensions in some cyanobacteria are called chromatophores.
