8
heterotroph and autotroph
9
carbon from organic carbon source
10
carbon from inorganic source
11
chemotroph and phototroph
12
energy from chemicals, organic carbon
13
energy from photosynthesis
14
energy source, conversion of nutrients from other organisms, metabolizing organic matter from the dead, ultilizing tissues, fluids from a live host
15
Protozoa, fungi, bacteria, and animals
16
energy source from sunlight or organic matter
17
purple and green photosynthesis bacteria
18
growth only occurs without the presence of oxygen
19
growth is best with oxygen but can survive without
20
growth only occurs in the presence of oxygen
21
oxygen has no effect on growth
22
growth only occurs in low concentration of oxygen
23
diffusion moves solvents and osmosis moves water
24
does not use energy, is affected by temperature, pressure, and steepness of the gradient
25
does not use energy, water moving from inside to outside of cell or vice versa, is affected by amount of solvent and where the solvent is
26
it is balanced, water concentration is the same inside and outside the cell
27
solute concentration is low outside the cell while water is high causing the cell to swell.
28
yes
29
cell bursting from to much water
30
solute concentration is higher outside the cell while water is low causing the cell to shrink.
31
loss of water
32
the cell dying from loss of water
33
does not use energy, moves from areas of higher concentration toward areas of lower concentration
34
protein assists the solutes in moving across the cell whether outside or inside the cell, movement of solutes from high to low concentration with protein helper
35
uses energy, moves wherever they want
36
facilitated diffusion but with energy and solutes can move from high to low and low to high concentrations
37
this uses a protein carrier and chemically alters the solute to move
38
brings nutrients inside the cell
39
cellular eating (ingesting solids)
40
cellular drinking (ingesting liquids)
41
lowest temp that permits a microbes growth and metabolism
42
highest temp that permits a microbes growth and metabolism
43
promotes the fastest rate of growth and metabolism (ideal temp)
44
psychrophiles, psychrotrophs, mesophiles, thermophiles, extreme thermophiles
45
optimum temp below 15°C (59°F), capable of growth at 0°C (32°F)
46
optimum temp 15-30°C (59-86°F), capable of growth at 0°C (32°F)
47
optimum temp 20-40°C, most human pathogens (68-104°F)
48
optimum temp greater than 45°C (115°F)
49
optimum temp greater than 80°C (176°F)
50
increase in salt or sugar
51
require high osmotic pressure
52
pressure caused by movement of water
53
tolerate high osmotic pressure
54
staphylococcus aureus, can grow in media containing 0.1%-20% salt
55
between 6.5-7.5
56
between 5 and 6
57
the reproduction of prokaryotes
58
1. a young cell exist, 2. a parent cell enlarges it’s cell wall, cell membrane, and overall volume, 3. septum wall grows inward and chromosomes are pulled in opposite directions of the cell, 4. the septum is synthesized completely through the center of cell resulting in two cell chambers, 5. finally two different physical cells with the same DNA
59
doubling time
60
time required for a complete fission cycle
61
exponential growth
62
2
63
microbe inhabits a new place
64
all nutrients available/stable environment leads to increase in cells
65
number of cells produced equals number of cells that died
66
nutrients become unavailable or environment becomes unstable causing cell to die
67
plate counts and turbidometry
68
direct count and enumeration of bacteria
69
after incubation count the colonies on plates that have 30-300 colonies
70
count all cells present, automated (coulter counter) or manual (you count one by one)
71
it’s a estimation using the degree of cloudiness, very cloudy= more microbes
72
spectrophotometer
73
a tool used to find degree of cloudiness
