| blue-green bacteria | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments.

According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |
