Chara is a genus of green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures. They are found in fresh water particularly in limestone areas throughout the northern temperate zone where they grow submerged attached to the muddy bottom. They prefer less oxygenated and hard water and are not found in waters where mosquito larvae are present.[citation needed] They are covered with calcium carbonate deposits.
