Plants are currently considered to be part of the supergroup within Eukarya, Archaeplastida. All members of this group are photosynthetic and include unicellular, colonial, and multicellular organisms. The major groups of this supergroup are glaucophyte algae, green algae, red algae, stoneworts, and plants. Glaucophyte Algae Glaucophyte algae (Phylum Glaucophyta) are unicellular freshwater algae, and are thought to resemble a very ancient ancestor of plants. Study of these organisms gives us clues to the origin of photosynthesis within Archaeplastida. The current...
