1A division of microorganisms that are related to the bacteria but are capable of photosynthesis. They are prokaryotic and represent the earliest known form of life on the earth.
- Class Cyanophyceae, kingdom Eubacteria
- That is, all Cyanobacteria and algal chloroplasts are, together, all of the descendants of some unique common ancestral cyanobacterium.
- Only Aquificales and Cyanobacteria do not present evidence of such a structuring, possibly because of a sampling effect, since only a few bacteria of these phyla have been presently sequenced.
- The significant buildup probably began about two billion years ago, with the appearance of Cyanobacteria.
1.1 (as plural noun cyanobacteria) Microorganisms of the Cyanobacteria division. Also called blue-green algae.
- Unlike any other flagellate algae, they contain phycobilins as accessory photosynthetic pigments, as do red algae and cyanobacteria.
- We conclude that there is no evidence available to support assignment of Halysis either to chlorophyte algae or to cyanobacteria.
- In Florida scrub, soil crusts include algae, cyanobacteria, and diatoms.
