There are many different one celled green organisms, but one of the most important to us is the blue-green algae, better known as cyanobacteria. These creatures are responsible for most of the free oxygen in our atmosphere.

Single-celled Algae, which can manifest as many different breeds of green aquatic plants having no true root structure or stem, and can be quite extensively spread over bodies of water despite being a single-celled organism. "Pond Scum"and seaweed are two types of single-celled aquatic algae, which are commonly observed in nature and are typically green. Blue-Green algae -- also known as Cyanobacteria -- is also a very common green aquatic plant, and interestingly, it was also the first successful single-celled organism to evolve on planet Earth.
