Definition:
Group of unrelated simple organisms that contain chlorophyll and live in aquatic ecosystems. Formerly regarded as plants, algae are now classified as members of the kingdom Protoctista. The organisms formerly known as blue-green algae are now classified as bacteria. [Adapted from Dic. of Biology, 3rd ed., Oxford Univ., 1996]
