Plasma Membrane
.Lipid Bilayer
.Selectively Permeable
Bacterium Cyptoplasm
. Maintains shape
.cytosol - h2o protein salt
. Ribosomes
. Where reactions occured
Cell wall
. Peptidoglycan
. Maintains shape
. Lipopolysaccharide
. Cyptoplasmic membrane
. Outer membrane
Frimbriae
. Could be 1000 on a cell
. Adhesion to host tissue and faviourable environments
Flagella
. Movement
Flagella
. Movement
Ribosomes
. 70s
. Smaller than eukaryotic
. Two subunits
. Proteins + RNA
. No membrane
. Synthesises proteins
Plasmid
. Extra chromasonal DNA
Nucleoid
. Controls activity + reproduction
. Instructions of protein symphesis
Pili
. Sex pili and type IV
. Aids in resisting phagocytosis
. Connects cells for conjugation.

Digestable
Aids against phagocytosis
Shields cell form toxins (detergents)
