Cyanobacteria ə, also known as Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. The name `cyanobacteria` comes from the color of the bacteria (κυανός (kyanós) = blue). They are often called blue-green algae, but some consider that name a misnomer as cyanobacteria are prokaryotic and algae should be euk.....

<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. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nit...

(= Cyanophyta) 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 phycobilins. Found as single cells, colonies or simple filaments. In Anabaena , in which the cells are arranged as a filament, heterocysts capable of nitrogen-fixation occur at regular intervals. According to the endosymbiont hypothesis Cyanobacteria are the progenitors of chloroplasts.
