Where do green unicellular algae live? What is the structure of chlamydomonas?
Green algae live in salt and fresh water, on land, on the surface of trees, stones or buildings, in damp, shaded places. Species living out of water are dormant during a drought. Chlamydomonas is a unicellular green pear-shaped alga. It moves in water with the help of two flagella located at the anterior, narrower end of the cell. Outside, chlamydomonas is covered with a transparent membrane, under which are located the cytoplasm with a nucleus, a red “eye” (a light-sensitive body of red color), a large vacuole filled with cell juice, and two small pulsating vacuoles. Chlorophyll and other pigments in Chlamydomonas are located in a large bowl-shaped plastid, which is called a chromatophore in algae (translated from Greek – “light-carrying”). Chlorophyll, contained in the chromatophore, imparts a green color to the entire cell.
