9 Helps an organism maintain homeostasis by controlling what enters or leaves the cell
10 What is the cell membrane?
11 Causes the concentration of molecules to be the same throughout a space
12 What is diffusion?
13 State that exists whenever molecular concentration is the same throughout a space
14 What is equilibrium?
15 When the concentration of solutes inside & outside the cells is equal
16 What is isotonic?
17 What is one example of something your body can lose homeostasis over?
18 Examples will vary?
19 Universal Solvent
20 What is water?
21 Property that makes water such a good solvent
22 What is polarity?
23 Solute concentration that causes water to move into the cell
24 What is hypotonic?
25 Direction water moves in passive transport
26 What is down the concentration gradient?
27 Prefix that refers to a high solute concentration & low water concentration outside the cell
28 What is hyper-?
29 Facilitated diffusion is “facilitated” by…
30 What are proteins?
31 Type of proteins that aid facilitated diffusion
32 What are carrier/trans port proteins?
33 Direction across concentration gradients that movement goes with no energy
34 What is higher to lower?
35 This happens to a transport protein molecule when it binds to ATP
36 What is change shape?
37 Type of molecules that move by facilitated diffusion
38 What are molecules too large to get through cell membrane?
39 When O2 and CO2 goes through membrane
40 What is diffusion?
41 Direction molecules diffuse across a cell membrane
42 What is high to low concentration?
43 Water movement across a cell membrane
44 What is osmosis?
45 Point where molecules continue to move without a concentration gradient
46 What is equilibrium?
47 Solutions with low concentrations of dissolved substances
48 What is hypotonic?
49 Required by cells to move materials by active transport
50 What is ATP or energy?
51 Direction of Movement across a membrane during active transport
52 What is low to high concentration?
53 Act as cell membrane “pumps”
54 What are carrier proteins?
55 Act to help a cell recognize itself
56 What is cell surface markers/carboh ydrates?
57
58 A plant is put in a hypertonic solution of sugar what organelle will shrink?
59 What is the vacuole?
60 Condition of the cytosol if the outside of the cell is hypotonic
61 What is hypertonic?
62 A multicellular organism’s response to being in a hypotonic solution
63 What is pumping out solutes?
64 Direction of water movement when the concentration of dissolved molecules outside the cell is lower than inside
65 What is water moving into the cell?
66 Molecules soluble in this can diffuse through the cell membrane
67 What are lipids?
68 Condition caused whenever plant cells lose turgor pressure and wilt
69 What is plasmolysis?
70
71 Transport
72 Kinetic energy of molecules
73 What is the energy for passive transport?
