17Sticky, gel-like layer surrounding the cell
- Made mostly of glycoproteins- AGlycocalyx
- Bcapsule
- CBiofilm
- Dcytoplasm
18cells release this coating so that cells can stick to something, say, tissues…useful for them to attach to things
- ABiofilm
- Bcapsule
- CGlycocalyx
- Dglue layer
19Glycocalyx
- Two layers
- not organized and a weak coating, loosely attached to the cell surface- ASlime layer:
- BCapsule
- CBiofilm
- Dcytoplasm
20-Plaque on teeth that protects bacteria from becoming dislodged
-Responsible for persistent colonization of catheters, IUDs, pacemakers, and other implanted medical devices- Abiofilm
- Bslime layer
- Cvisceral layer
- Dbio acids
- Esecretions
21biofilms are part of which layer
- Aslime
- Bcapsule
22provides resistance to phagocytosis (the cells can stop the ingestion of phagocytes; and in turn they cause an infection)
- provides adherence as well- ACapsule
- BSlime layer

- Aa protein called flagellin
- Bmicrotubules
24in proks, flagella
- Arotate/spin
- Bmove in a whip-like mvmnt
