Green algae - Definition, Glossary, Details - Oilgae
The "green algae" is the most diverse group of algae, with more than 7000 species growing in a variety of habitats. The "green algae" is a paraphyletic group because it excludes the Plantae. Like the plants, the green algae contain two forms of chlorophyll, which they use to capture light energy to fuel the manufacture of sugars, but unlike plants they are primarily aquatic. Because they are aquatic and manufacture their own food, these organisms are called "algae," along with certain members of the Chromista, the Rhodophyta, and photosynthetic bacteria, even though they do not share a close relationship with any of these groups.Source

A common algae type in estuaries, with nucleated cells and photosynthetic pigments contained in organelles called chloroplasts. Link
Algae that are clear green in color; often growing on wet ricks or damp wood or the surface of stagnant water. Link
Chlorophyta: Green Algae: Green algae may be unicellular, multicellular, colonial or coenocytic. They have membrane-bound chloroplasts and nuclei. Most species are aquatic and are found commonly in freshwater
Green Algae: The term 'algae' is used for some lower plants and many, often unrelated groups of microorganisms that are able to perform photosynthesis.
