25
what is the chloroplast?
only in plant cells and helps with photosynthesis and trapping sunlight.
26
what is the inner cell called?
ICF or intracellular fluid
27
what is the outer cell called?
ECF or extracellular fluid
28
what is fluid?
the flexible part of a cell
29
what is mosaic?
a collection of different substances held together
30
What is a channel protein?
tunnels in the membrane to let big particles pass through
31
What is a carrier protein?
Opens and closes to let big specifically shaped molecules through
32
What are phosphates
(Head) really like water next to the ICF and ECF
33
what are lipids?
Tail- hates water and not near ECF or ICF
34
What are the four particle model of matter rules?
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
35
How are particles moving?
Fastest in gas and slowest in solids
36
what is the space between particles?
most in gases and least in solids
37
what is the phosphlipid bilayer?
it two layers of phosphates
38
what is concentration?
the ratio of solute to solvent in a solutio
39
what is a solute?
the material being dissolved
39
What is a solvent?
the material being used to dissolve things in
39
What is a solution?
the mixture of solute and solvent
40
What is a concentration gradient?
it only occurs when theres a different concentration on both sides and movement is always going down along or with it
41
What is impermeable?
allows nothing through
42
What is semi permerable?
allows some through (humans)
43
What is permeable?
allows all through
44
What is passive transport?
includes diffusion, facillitated diffusion and osmosis. no energy required, goes along the gradient, high to low
45
What is active transport?
includes exocytosis, and endosytosis. needs energy, goes against gradient, low to high
46
what is diffusion like?
it like flowing downstream
46
what factors affect diffusion?
size of particles must be small, concentration difference (bigger faster), tempeture (hotter faster), surface area (more faster), and state (gas fastest)
47
what is facilitaded diffusion?
Its diffusion with the help of some proteins that help molecules that otherwise could not get thorough to go through
48
What is osmosis?
its the same prosses as diffusion but specifically with water?
49
Where does water always go?
were the higher concentration is to help balance
50
what is hypertonic?
where the solution is higher then the solute. water will move out of the cell
51
What is isotonic?
where the solution and solute are equal. water moves in and out
52
What is hypotonic?
the solvent is lower than the solute so water will move into the cell
53
what does the golgi apparatus do in active transport?
it forms a vesicle around large waste products that merges with the sell and releases the waste outside
54
what is -0?
this moves things into the cell
55
what is exosytosis?
this moves things out of the cell
56
what are the advantages of small cells?
requires less nutrients produces less waste
57
what are the disadvantages of small cells?
less surface area for intake of nutreints and getting rid of waste
58
what are the advantages of big cells?
more area for pulling in nutreints and getting rid of waste
59
what are the disadvantages of big cells?
requires more nutrients creates more waste
60
what is Surface area?
6S squared
61
What is volume?
S cubed
62
What is SA:V ratio?
6 divided by S (bigger SA and smaller V the better)
