Green algae
Scientific classification
Kingdom: Plantae or Protista

Green algae are microscopic protists. One can find them in all sorts of natural water: salt water, freshwater and brackish water. They are a convenient catch-all group, but are less used in classification today. They are not monophyletic: they are not all descended from a single ancestor.

The green algae are the large group of algae from which the higher plants developed.[1] They form a group, that can included among the Plantae or with the Protista.

The green algae include unicellular and colonial flagellates, usually but not always with two flagella per cell, as well as various colonial, coccoid, and filamentous forms. In the Charales, the closest relatives of higher plants, full differentiation of tissues occurs. There are about 6000 species of green algae.[2] Many species live most of their lives as single-cells, other species form colonies or long filaments.
