Mark all correct statements about the supergroup, Archaeplastida.
Archaeplastida includes all of the photosynthetic organisms on Earth
Archaeplastida includes only species that are descended from an ancestor that is thought to have become photosynthetic by engulfing a photosynthetic prokaryote
Archaeplastida includes all of the photosynthetic eukaryotes on Earth
Ans. Correct option- B, C. Archaeplastida is the supergroup of photosynthetic eukaryotes that have plastids derived from endosymbiosis of a photosynthetic prokaryotes (cyanobacteria).
The engulfment (more precisely, endosymbiosis) of photosynthetic cyanobacteria with the host cell gave rise to the eukaryotic cells with plastids.
All the photosynthetic eukaryotes on Earth, including land plants, green algae, red algae, etc. belong to the supergroup Archaeplastida because their plastid (chloroplast) is derived from symbiosis of cyanobacteria.
# Option A. Incorrect. Prokaryotic synthetic bacteria like cyanobacteria do not belong to Archaeplastida because they don’t have a plastid of prokaryotic symbiosis.
