Green Algae Description
Green algae (chlorophyta): This large and diverse group of algae can range from small, single-celled organisms to large, multicellular organisms and colonies. They are considered the closest ancestors to the land plants because they share common features, including the photosynthetic pigments chlorophyll a, chlorophyll b, beta carotene, and cellulose-rich cell walls. They are also the only algal group to produce starch for food stores.
