Facultative

Back 3

Can grow with and without O2

Front 4

UV light

Back 7

Lethal to living cells

(DNA)

Front 8

Isotonic

Back 8

Same concentration in and out of cell no net movement

Front 9

Hypertonic

Back 9

Higher solute concentration outside of the cell

Net movement of water is out of the cell

Front 10

Hypotonic

Back 10

Lower solute concentration outside of the cell

Water enters the cell

Front 11

Lyse

Back 11

Water enters cell and burst in hypotonic environment

Front 12

Crenate

Back 12

Water leaves cell and shrivals in hypertonic environment

Front 13

Front 15

Acidophile

Back 15

Acid loving

Front 16

Saccharomyces cerevisiae

Front 28

Anaerobic broth

Back 28

Fluid Thioglycollate broth

Front 29

Bacillus subtilis survives longer in uv light then staph

Back 29

Because it has an endospore

Front 30

Staph is a (prefered environment)

Back 30
