Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis.
A prokaryotic cell contains a single membrane and therefore, all the reactions occur within the cytoplasm. They can be free-living or parasites.
Prokaryotic cells have different characteristic features such as:
