Study Notes
Bacterial Glycocalyx
- Glycocalyx composition and thickness vary among different bacteria
- Composition can be a loose sheath (slime layer) in some bacteria
- Composition can be thick and tough (capsule) in other bacteria
Bacterial Cell Wall
- Determines the shape of the bacterial cell
- Provides strong structural support to the bacterium
- Prevents the bacterium from bursting or collapsing
