blue-green algae

blue-green algae
cyanobacterium cyanobacterium pl. cyanobacteria cyanobacteria [from the pigment phycocyanin.] any of a group of photosynthetic autotrophic prokaryotic microorganisms possessing characteristics of both bacteria and plants. When classed as bacteria, they are assigned to the Cyanobacteria; when classed as plants, they are assigned to the Cyanophyta. They were earlier named {blue-green algae}, a term less used now in technical discussions. Since the chlorophyll within the cyanobacteria is diffused throughout the cell, rather than being contained in chloroplasts, they are no longer thought of as true plants. [PJC]
