All archaeplastidans have plastids (chloroplasts) that carry out photosynthesis and are believed to be derived from endosymbiotic cyanobacteria. In … 展开

Perhaps the most ancient remains of Archaeplastida are putative red algae (Rafatazmia) within stromatolites in 1600 Ma (million years ago) rocks in India, as well as possible alga fossils ( 展开
