The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːrkɪˈplæstɪdə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes.
The Archaeplastida are one of the major evolutionary lineages of photosynthetic organisms, and arguably the most important for animals, including humans, because the ancestors of one group (green algae and plants) was able to invade land and set the stage for the evolutionary movement onto land of many animal groups.
Archaeplastida (‘ancient plastids’) are the group containing essentially all of the primary algae (i.e., with plastids of primary endosymbiotic origin – see above), and the great majority of living species in this assemblage are photosynthetic.
The Archaeplastida is a monophyletic lineage of eukaryotic photoautotrophs. They have plastids acquired by primary endosymbiosis with a cyanobacterium. Members of this group have supplied plastids by secondary endosymbiosis to other photoautotrophic eukaryotic lineages (Euglenids, Alveolates, and Stramenopiles). Archaeplastida includes:
