Green algae are eukaryotes characterized by chlorophylls a and b as the major photosynthetic pigments (but colorless, heterotrophic taxa are also present [e.g., Polytoma, Polytomella, and Hyalogonium]), starch (α-1,4 and α-1,6 polymer of glucose) located within the chloroplast as the major storage product, and flagella of the whiplash (smooth) type (e.g., Bold and Wynne, 1985). 1.

Strain variation: Biological N 2 fixation in nature or agricultural ecosystem is rarely limited by a lack of N 2, fixing micro-organisms. In the tropics, however, they are mostly subtidal, growing as epiphytes on seagrasses, within the crevices of rock and coral reefs, or occasionally on dead coral or sand. Complex algae live at different depths of water based on the penetration of light colors into water. Algae 1.

Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. The role of these pigments is to absorb light - In water the problem is that red and violet wavelengths do not penetrate the vertical column very well. Red Algae Pigment, depth, food and products Pigment The red color of the algae comes from the presence of phycobilin or phycoerythin - a pigment.

A new form of fuel can literally called green, as it derives from green algae.Algae, often seen growing on bodies of water, is a tiny plant with a rapid growth rate. Historically, Hans Gaffron made the first observation of hydrogen metabolism in green algae (Gaffron, 1939, 1944).Upon exposure to hydrogen of anaerobically adapted cells, he observed uptake of molecular H 2 by the algae and a concomitant CO 2 reduction in the dark. The reverse reaction, e.g. green and brown algae. Like other algae, green algae serve as an important food source for herbivorous marine life, such as fish, crustaceans, and gastropods, including sea snails.Humans use green algae as food, too. Marine, and terrestrial. Presentation Summary : Green Algae. In temperate regions such as California, red algae are common in the intertidal zone. Planktonic blue-green algae can kill fish, and is the most noxious form of aquatic growth that we deal with here in North Texas. Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960.
