Solution

Prokaryotic cell:

  1. Prokaryotic cells are single-celled microorganisms known to be the earliest on earth.
  2. Prokaryotes include Bacteria and Archaea.
  3. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis
  4. In most bacterial species, the cytoplasmic membrane is encased in a hard material called peptididoglycan.
  5. It helps maintain cell shape throughout the life cycle and shields bacterial cells from environmental stress.
  6. Prokaryotic cell walls may be composed of peptidoglycan (bacteria) or pseudopeptidoglycan (archaea).
  7. Gram-positive bacterial cells are characterized by a thick peptidoglycan layer.
  8. Gram-negative bacterial cells are characterized by a thin peptidoglycan layer surrounded by an outer membrane.
