Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum consisting of free-living bacteria as well as the endosymbiotic plastids which appear sister to Gloeomargarita. They commonly obtain their energy through photosynthesis. They are the only photosynthetic prokaryotes able to produce oxygen. The name cyanobacteria comes from the color of the bacteria (Greek: κυανός, romanized: kyanós, lit. 'blue'). Cyanobacteria, which are prokaryotes, are also called "blue-green algae", though some modern botanists restrict the term algae to eukaryotes. Cyanobacteria appear to have originated in freshwater or a terrestrial environment.
