prokaryoric cells

• • bacteria
  • much smaller than eukaryotic
  • no membrane bound organelles
  • 70s ribosomes
  • no nucleus, single circular bacterial chromosome free in cytoplasm
  • cell wall containing peptidoglycan
• cell wall

  • peptidoglycan
  • strength and support
• slime capsule

  -protective slime layer

  • protects bacteria from drying out
  • retain moisture and adhere to services
• plasmids

  • small loops of DNA
  • loose and not associated with proteins/histones
• flagellum

  • tail like
  • rotates allowing movement
• pili

  • hair like structures
  • attach to other bacteria to exchange plasmids
• circular DNA

  • small circular strands of DNA
  • not contained in membrane
