Volvox is a freshwater algae which is found in ponds , ditches and even in shallow puddles. The three species are Arthrospira platensis, A. fusiformis, and A. maxima.. Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food. Green algae have cell walls made of cellulose and are photosynthetic. Once the live algae are treated, the plantlike organism dies. This means that it’s a natural source of nutrients and vitamins. Chlamydomonas species can become so abundant as to colour fresh water green, and one species, C. nivalis, contains a red pigment known as hematochrome, which sometimes imparts a red colour to melting snow.

They are nowadays used in the treatment of wastewater and for controlling pollution. That is, they are photoautotrophs. Green seaweed may be found in the marine or freshwater habitats. It is an aquatic living organism that requires sunlight and nutrition to grow other plants likewise. Algae have photosynthetic nutrition. Green Seaweed: Green seaweed belongs to the phylum Chlorophyta. Examples of single-cell blue green algae are Chroococcus and Gloeocapsa. Laminaria digitata. Golden algae used to make algae-based omega-3 supplements do not appear to contain BMAA. Mainly marine algae have been used as food and medicine for many centuries .they are not only used as food but also used as extracts in food, dairy, cosmetics, and industrial uses. Symbiosis in lichens is the mutually helpful symbiotic relationship of green algae and/or blue-green algae (cyanobacteria) living among filaments of a fungus, forming lichen.. In turn, they are related to terrestrial plants. Green algae have dark- to light-green coloration that comes from having chlorophyll a and b, which they have in the same amounts as "higher plants"—the plants, including seed plants and ferns, that have well-developed vascular tissues that transport organic nutrients. Green algae may be found in marine or freshwater habitats, and some even live on land, growing on soil, trees, or rocks. Algae are the plants with the simplest type of organization.
