Fiction:Pnolthanus/Species/Cells

Viridae is the name for a large group of photosynthetic organisms that are not necessarily genetically related but serve a similar ecological function. Viridae are aquatic may be either unicellular as with phytoplankton or multicellular as with marine plants and seaweeds. They are a primary converter of CO2 into oxygen by way of photosynthesis, producing a significant fraction of the oxygen on Pnolthanus. When conditions are right, large green blooms of viridae can be seen in the oceans ad even from space.
