Cyanobacteria, light micrograph. These are filaments of cyanobacteria, made up of individual cells (round) that clump together. Cyanobacteria (formerly known as blue-green algae) are a photosynthesising form of bacteria. They were among the first lifeforms to appear on Earth, Âand oxygenated the atmosphere. They are found worldwide in most habitats, including oceans, fresh water, and soil.
