Algae and Seaweeds

Algae are found in both fresh and marine waters. They are usually thought of as simple aquatic plants which do not have roots, stems or leaves, have primitive methods of reproduction and are carbon fixing, oxygenating organisms. They range in size from microscopic organisms, visible only under a microscope, to large seaweeds which may be metres in length. A Seaweed is a multi-cellular algae which has little or no vascular tissues; it is a dense green, brown or red sea vegetable, which can be used as part of a healthy diet and is used in herbal medicines in many traditional cultures.
