| 1638710497 | Phospholipid | molecule that has both a hydrophillic region and hydrophobic region |  | 0 |
| 1638710498 | Phospholipid bilayer | a double layer of phospholipids that makes up a plasma membrane |  | 1 |
| 1638710499 | Integral Proteins | Proteins that extend through the phospholipid bilayer. |  | 2 |
| 1638710500 | Peripheral Proteins | A protein loosely attached to the surface of a membrane | | 3 |
| 1638710501 | cholesterol | steroid present in the plasma membranes of animal cells. A large amount of this in a phospholipid bilayer at High Temperatures reduces membrane fluidity, but at Lower Temperature prevents the membrane from solidifying. |  | 4 |
| 1638710515 | Selective Permeability | Allows some substances to cross more easily than others | 5 | |
| 1638710502 | Diffusion | the movement of molecules from an area of higher concentration to an area of lower concentration, so that they spread out evenly reaching equilibrium |  | 6 |
| 1638710516 | Osmosis | The diffusion of water across a selectively permeable membrane | 7 | |
| 1638710517 | Concentration Gradient | a difference in the concentration of a substance across a space | 8 | |
| 1638710503 | Transport Proteins | proteins that help to transport substances across cell membranes |  | 9 |
| 1638710518 | Passive Transport | movement of materials through a cell membrane without using energy | 10 | |
| 1638710504 | Isotonic | a solution whose solute concentration equals that inside a cell; the cell will not change |  | 11 |
| 1638710505 | Hypertonic | the solution with the greater concentration of solutes than that inside the cell; the cell will lose water to its environment--> Cell will shrivel up |  | 12 |
| 1638710506 | Hypotonic | the solution with the lower concentration of solutes than that inside the cell; water will enter the cell -> Cell will swell and burst |  | 13 |
| 1638710507 | Plasmolysis | As a plant cell shrivels its plasma membrane pulls away from the wall |  | 14 |
| 1638710508 | Facilitated Diffusion | passive transport of ions or polar molecules across a plasma membrane by transport proteins | | 15 |
| 1638710509 | Active Transport | transport of a substance through a cell membrane against the concentration gradient; requires energy |  | 16 |
| 1638710510 | Sodium-Potassium Pump | a carrier protein that uses ATP to transport sodium ions out of a cell and potassium ions into the cell against the concentration gradient; active transport, requires energy |  | 17 |
| 1638710511 | Exocytosis | process by which a cell releases large amounts of material by vesicles |  | 18 |
| 1638710519 | Endocytosis | the movement of a substance into a cell by a vesicle | 19 | |
| 1638710512 | Phagocytosis | A type of endocytosis in which microbes are taken in by immune cells of animals (mainly by macrophages) |  | 20 |
| 1638710520 | diaphragm | controls the amount of light coming through the stage | 21 | |
| 1638710513 | Prokaryotic cell | cell lacking a nucleus and most other organelles; found only in bacteria |  | 22 |
| 1638710514 | Eukaryotic cell | cell with a nucleus (surrounded by its own membrane) and other membrane-bound organelles |  | 23 |
