The blue-green ‘algae’, probably the most familiar bacterial clade, and one of the few to be recognised before the advent of molecular data (the other was the [[Spirochaetes]]). Characterised by oxygenic photosynthesis with [[chlorophyll]] ''a''. Flagella absent. A single genus, ''Gloeobacter'', is recognisably basal to all others in lacking [[thylakoid]]s. The clade Phycobacteria contains all other cyanobacteria, and has the chlorophyll contained in thylakoids. Phycobacteria have traditionally been divided into five orders on the basis of morphological colony characters. [[Chloroplast]]s are derived from Phycobacteria, though from which subclade is still unknown.
