Q

what is the cetrolites?

A

there only in animal cells and help with cell division.

31
Q

what is the cell wall?

A

only in plant cells and helps to provide strength and support with a ridgid edge

32
Q

what is the large vesicle?

A

only in plant cells and helps to store water and nutrients

33
Q

what is the chloroplast?

A

only in plant cells and helps with photosynthesis and trapping sunlight.

34
Q

what is the inner cell called?

A

ICF or intracellular fluid

35
Q

what is the outer cell called?

A

ECF or extracellular fluid

36
Q

what is fluid?

A

the flexible part of a cell

37
Q

what is mosaic?

A

a collection of different substances held together

38
Q

What is a channel protein?

A

tunnels in the membrane to let big particles pass through

39
Q

What is a carrier protein?

A

Opens and closes to let big specifically shaped molecules through

40
Q

What are phosphates

A

(Head) really like water next to the ICF and ECF

41
Q

what are lipids?

A

Tail- hates water and not near ECF or ICF

42
Q

What are the four particle model of matter rules?

A
  1. All matter is made up of particles
  2. particles are always moving
  3. particles are attracted to each other
  4. particles have spaces in between them
43
Q

How are particles moving?

A

Fastest in gas and slowest in solids

44
Q

what is the space between particles?

A

most in gases and least in solids

45
Q

what is the phosphlipid bilayer?

A

it two layers of phosphates

46
Q

what is concentration?

A

the ratio of solute to solvent in a solutio

47
Q

what is a solute?

A

the material being dissolved

47
Q

What is a solvent?

A

the material being used to dissolve things in

47
Q

What is a solution?

A

the mixture of solute and solvent

48
Q

What is a concentration gradient?

A

it only occurs when theres a different concentration on both sides and movement is always going down along or with it

49
Q

What is impermeable?

A

allows nothing through

50
Q

What is semi permerable?

A

allows some through (humans)

51
Q

What is permeable?

A

allows all through

52
Q

What is passive transport?

A

includes diffusion, facillitated diffusion and osmosis. no energy required, goes along the gradient, high to low

53
Q

What is active transport?

A

includes exocytosis, and endosytosis. needs energy, goes against gradient, low to high

54
Q

what is diffusion like?

A

it like flowing downstream

54
Q

what factors affect diffusion?

A

size of particles must be small, concentration difference (bigger faster), tempeture (hotter faster), surface area (more faster), and state (gas fastest)

55
Q

what is facilitaded diffusion?

A

Its diffusion with the help of some proteins that help molecules that otherwise could not get thorough to go through

56
Q

What is osmosis?

A

its the same prosses as diffusion but specifically with water?

57
Q

Where does water always go?

A

were the higher concentration is to help balance

58
Q

what is hypertonic?

A

where the solution is higher then the solute. water will move out of the cell

59
Q

What is isotonic?

A

where the solution and solute are equal. water moves in and out

60
Q

What is hypotonic?

A

the solvent is lower than the solute so water will move into the cell

61
Q

what does the golgi apparatus do in active transport?

A

it forms a vesicle around large waste products that merges with the sell and releases the waste outside

62
Q

what is -0?

A

this moves things into the cell

63
Q

what is exosytosis?

A

this moves things out of the cell

64
Q

what are the advantages of small cells?

A

requires less nutrients
produces less waste

65
Q

what are the disadvantages of small cells?

A

less surface area for intake of nutreints and getting rid of waste

66
Q

what are the advantages of big cells?

A

more area for pulling in nutreints and getting rid of waste

67
Q

what are the disadvantages of big cells?

A

requires more nutrients
creates more waste

68
Q

what is Surface area?

A

6S squared

69
Q

What is volume?

A

S cubed

70
Q

What is SA:V ratio?

A

6 divided by S (bigger SA and smaller V the better)
