Cyanobacteria /sˌænbækˈtɪəriə/, forby kent as Cyanophyta, is a phylum o bacteria that obtain thair energy throu photosynthesis.[4] The name "cyanobacteria" comes frae the colour o the bacteria (Greek: κυανός (kyanós) = blue). Altho eften cried blue-green algae, that name is a misnomer as cyanobacteria are prokaryotic an algae are eukaryotic.

Bi producin oxygen as a gas as a bi-product o photosynthesis, cyanobacteria are thoucht tae hae convertit the early reducin atmosphere intae an oxidizing ane, which dramatically changed the composeetion o life furms on Yird bi stimulatin biodiversity an leadin tae the near-extinction o oxygen-intolerant organisms. Accordin tae endosymbiotic theory, the chloroplasts foond in plants an eukaryotic algae evolved frae cyanobacterial ancestors via endosymbiosis.
