Cyanobacteria:
Cynobacteria is a type of bacteria, played an important role in the history of Earth and in ocean processes, including the development of stromatolites. Living in colonies, the cyanobacteria produced oxygen during the process of photosynthesis, which generated the oxygen in the Earth's atmosphere that many living beings require today. Although cyanobacteria also are called "blue-green algae," it is important to remember that cyanobacteria are relatives of bacteria and not algae. They are, however, related to the chloroplasts within algae; the chloroplasts used by some plants to produce food are actually cyanobacteria living within plants' cell walls.

Stromatolites are layered, mushroom-shaped structures formed by lime secreted by cyanobacteria. Fossilized stromatolites have provided scientists with critical information about the earliest development of life on Earth. Living stromatolites are among the unique forms......
