, 9. Pili
Answer > are protein fibers extending from the surface of many bacteria
10. Pili help the cell...
Answer > Attach cells to surfaces and form biofilms and microcolonies
11. conjugation pili are used to
Answer > transfer genetic material between cells
12. Glycocalyx
Answer > is an outer layer external to the cell wall that is an adhering layer of polysaccharides (sometimes small
proteins)
13. Capsule
Answer > A thick glycolayx bound to the cell
14. A slime layer
Answer > A thinner, dittuse layer of polysaccharides that protects cells from the environment, and allows them to attach
to surfaces
15. bacterial cell wall
Answer > a tough and protective external shell made of peptidoglycan
16. The cell wall's functions
Answer > protects the cell from injury, and to maintain cell shape and water balance

Answer > periplas- mic space
20. Porins
Answer > in outer membrane, selectively allow small molecules into the periplasmic space
21. represents the interface between the cell environment and the cell cyto- plasm
Answer > The cell membrane
22. The fluid mosaic model
Answer > It is a fluid layer of phospholipid and protein
23. ...form a permeability barrier
Answer > Hydrophobic fatty acid chains in the phospholipids
24. Membrane proteins perform or aid in many functions
Answer > Cell wall synthesis, Energy metabolism, DNA replication, Sensation of stimuli, Molecule
transport
25. Antimicrobial substances may...
Answer > ...disrupt or dissolve the bilayer
26. Binary Fission Answer > The cell doubles in mass, DNA replicated in the two strands separate
