5Which has 70s ribosomes (smaller ones)
- AProkaryotic
- BEukaryotic
6Multiple reproduction types: mitosis, fission, budding (v. binary fission)
- AProkaryotic
- BEukaryotic
7Bacteria generally reproduce by dividing into two equal cells; this process is called
"divide into two cell”- Abinary fission
- Bmitosis
- Cbifussion
- DMultiple fission
- EBudding
8t/f
single of Spirillum is spirilla- At

- AVibrio
- BSpirochete
- CSpirillum
- DBacillus
- Ecillio
11Pleomorphic bacteria
- Ahave a slightly curved rod shape.
- Bare flexible.
- Creproduce by snapping division.
- Dvary in size and shape.
12T/F
Cells need to be in pairs in order to function- At
- Bf
13what are the different arrangements of cocci?
- A-diplococci: pairs
- B-single
- C-tetrads groups of four
- D-staphylococi irregular clusters
- Estreptococci: chains
- F- pylori clusters
- G- Lophotrichous
14Bacterial arrangements

- Btetrads
- Cstaphylococi
- Dstreptococci
15Bacterial arrangements
- irregular clusters- Adiplococci
- Btetrads
- Cstaphylococi
- Dstreptococci
16Bacterial arrangements
- chains- Atetrads
- Bstaphylococi
- Cstreptococci
- Dsingle
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
23in proks flagella are made of
- Aa protein called flagellin
- Bmicrotubules
24in proks, flagella
- Arotate/spin
- Bmove in a whip-like mvmnt
25Axial filament (aka endoflagellum) are present on in
- Aspirochetes
- BSpirillum
- CBacillus
- DVibrio
26atypical prokaryotic
-naturally lack a cell wall
-sterols in the cell membrane stabilize the cell- AMycoplasma
- BMycobacterium
- CNocardia
- Dpseudomurein
27-long-chain of fatty acids
-Found in the cell walls of acid-fast bacteria
-Contribute to the pathogenicity of the bacteria due to its resistance to certain chemicals and dyes- AMycolic acid
- Bchemotaxi
- CTeichoic
- DMycobacterium
28What are the acid-fast bacteria?
- AMycobacterium
- BNocardia
- Cmycolic acids
- DMycoplasmas
29The genus Mycobacterium includes species responsible for
- Atuberculosis.
- Burinary tract infections.
- Cgastric ulcers.

30Cell wall with fatty acids (mycolic acid)
• High degree of resistance to chemicals and dyes- AMycobacterium and Nocardia
- BMycoplasma
- Cpolysaccharides
- Dpseudomurein
31in Archaea cell walls are made of what
- Apseudomurein
- BNAM and d-amino acids
- Cglycoproteins
- Dcomplex polysaccharides
32t/f
the membrane around a cell negative cell wall is the same as a plasma membrane- Afalse
- Btrue
