Green cyanobacteria
WebCyanobacteria get their name from the bluish pigment phycocyanin, which they use to capture light for photosynthesis. They also contain chlorophyll a, the same photosynthetic pigment that plants use. In fact the chloroplast in plants is a symbiotic cyanobacterium, taken up by a green algal ancestor of the plants sometime in the Precambrian. Cyanobacteria , also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name cyanobacteria refers to their color (from Ancient Greek κυανός (kuanós) 'blue'), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they … See more Cyanobacteria are a very large and diverse phylum of photoautotrophic prokaryotes.
