The algae are a large and very diverse group oforganisms that rangefrom minute single-celled forms to the giant marine kelps. They occupy a wide variety of habitats, including fresh water (lakes, reservoirs, and rivers), oceans, estuaries, moist soils,coastal spray zones, hot springs, snow fields and stone or concrete surfaces. In water, they can be planktonic, meaning suspended in the water and carried passively by the currents, or attached torocks, sediment, reservoir walls, or other plants.
