Archaeplastida. 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. From: Encyclopedia of Evolutionary Biology, 2016
The majority view at present is to order all eukaryotes into six supergroups: Excavata, Chromalveolata, Rhizaria, Archaeplastida, Amoebozoa, and Opisthokonta. The goal of this classification scheme is to create clusters of species that all are derived from a common ancestor.

Mar 25, 2021 · There are three main lineages with primary plastids: red algae, green algae (including land plants) and glaucophytes—altogether forming a large group known as Archaeplastida 3, 4.

Archaeplastida Consists mostly of photosynthetic algae; evolved from a heterotrophic ancestor that acquired a plastid via primary endosymbiosis of a cyanobacterium; this ancestor may be common to all groups within Archaeplastida, or multiple endosymbiotic events may have occurred.
