other term for cyano bacteria is "blue-green algae". it is called so because from the word "CYAN" meaning greenish-blue colour and they are classified as bacteria. Cyanobacteria contain the same kind of chlorophyll that is found in green plants, but it is distributed throughout the cell rather than confined in chloroplasts. Other pigments mask the chlorophyll in many species and impart a bluish or sometimes reddish colour.

Do you mean...
cyanobacteria
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
