5
Q
characteristics
A
- spirilli (spiral)
- bacilli (rod)
- cocca (round)
6
Q
Cyanobacteria
A
- gram - and photosynthesize
- responsible for introducing oxygen into the primitive atmosphere
- lack locomotion
- when commensals with fungi lichens form
7
Q
archae characteristics
A
- most are chemoautotrophs
- some mutualistic
- most commensalistic
- none to be parasitic
- none are photosynthetic
- may live in harsh conditions
8
Q
archae similarities and differences with domain bacteria and eukarya
A
- they don’t have peptidoglycan in cell walls like bacteria
- biochemically more like eukarya than bacteria
9
Q
gram stain
A
bacteria are commonly diagnosed using the gram stain procedure
gram +: retain and appear purple due to thick peptidoglycan layer
gram -: appear pink due to thin peptidoglycan layer
