Square

16

Rhizobium
Corynebacterium

Plemomorphic Bactria

17

Can have more than one genetically controlled shape

Pleomorphic

18

Sugar coat outside cell wall that is viscous and sticky.
Contains polysaccharide and/or polypeptide
Capsule if organized
Slime layer if unorganized

Glycocyx

19

Important virulence factor
Protect from from phagocytosis
Allows bacteria to attach to surfaces

Capsule
Structures external to cell wall

20

Treponema pallidum

Spirochete
Cause syphilis

21

Found in gram negative bacteria
Shorter straighter, thinner than flagella
Made of protein pilin

Fibriae
Pili

22

Joins cells for transfer of DNA from one cell to another

Pili
Sex pili

23

Enable cell to adhere to surfaces
If absent no colonization of bacteria no disease
Forms biofilms

Fimbriae

24

Cell wall composed of repeating monosaccharides N-acetulglucodamine and N-acetulmuraic acid

Peptidoglycan

25

Consists of many Layers of Peptidoglycan
Contains trichroic acids
Lipoteichoic-plasma membrane
Wall teichoic acid-linked to Peptidoglycan layer

Gram positive bacteria

26

Have one or few layers of Peptidoglycan
No teichoic acid in cell wall
Peptidoglycan present in peri plasm

Gram negative Bacteria

27

Contain pigments and enzymes for bacterial photosynthesis are found in plasma membrane

Chromtophores

28

Bacterial cells will shrink ms collapse as water leaves the cell by osmosis

Hypertonic solution

29

Cell with weak wall may burst
(Gram negative

Hypotonic solution
