Bacteria are very small in size, and many varieties. Some have evolved to be capable of photosynthesis (called photosynthetic bacteria). They contribute a large amount to primary production in certain parts of the oceans, and may
contribute up to 50% of the world's biomass.
Cyanobacteria (commonly called called blue-green algae) are photosynthetic algae common in marine and freshwater environments. Cyanobacteria contain chlorophyll while other forms of bacteria contain bacteriochlorophyll. Although bacteriochlorophyll resembles chlorophyll, it absorbs light of a longer wavelength than chlorophyll. Common kinds are cyanobacteria in the marine environment include golden algae and green algae.
