Cell Architecture of Prokaryotes (Bacteria)

There are two main classifications for cellular life: Prokaryotes, which are single-celled organisms without a nucleus and Eukaryotes, which are organisms whose cells have a nucleus.
Prokaryotes, whose estimated biomass is more than ten times greater than the biomass of eukaryotes, are found in two domains: Bacteria and Archaea.
SHARED FEATURES
  • Plasma membrane
  • Cytosol
  • Use DNA to store genetic information
  • Use ribosomes to synthesize proteins
PROKARYOTES ONLY
  • Circular chromosome found in nucleoid region of cell
  • Cell wall (made of different molecules than eukaryotic cell walls)
EUKARYOTES ONLY
  • Linear chromosomes in membrane bound nucleus
  • Membrane bound organelles
