| 8574236355 | Plasma membrane (cell membrane) | Regulates what enters and leaves the cell and separates the internal environment of the cell from the external environment |  | 0 |
| 8574236356 | Fluid Mosaic Model | Describes the following properties of the cell membrane: 1. cell membrane is fluid, flexible and moves. 2. cell membrane is composed of proteins, lipids and carbohydrates. |  | 1 |
| 8574236357 | Selectively permeable | The term to describe a cell membrane that allows some substances to pass, but not others |  | 2 |
| 8574236358 | Bilayer | The cell membrane is made of two layers of lipid molecules. |  | 3 |
| 8574236359 | Phospholipid | Makes up the cell membrane; has 1 head (hydrophilic) and 2 tails (hydrophobic) | | 4 |
| 8574236360 | Polar Head | part of the phospholipid that is attracted to water. |  | 5 |
| 8574236361 | Non-Polar Tail | Part of the phospholipid that is not attracted to water. |  | 6 |
| 8574236362 | Hydrophilic | Means "water lovings" Describes the heads (circle portion) of the phospholipids | | 7 |
| 8574236363 | Hydrophobic | Means water fearing. Describes the tails of the phospholipids | | 8 |
| 8574236364 | Protein | This component of the cell membrane are channels that transports substances. |  | 9 |
| 8574236365 | Carbohydrates | This component of the cell membrane allows different cells in your body to identify each other. | 10 | |
| 8574236366 | Concentration gradient | A difference in the concentration of solutes on one side of the cell membrane compared to the other side. |  | 11 |
| 8574236367 | Diffusion | The movement of molecules from an area of high concentration to area of low concentration. |  | 12 |
| 8574236368 | Osmosis | The diffusion WATER across a selectively permeable membrane. |  | 13 |
| 8574236369 | Facilitated diffusion | The type of cell transport in which large molecules (like glucose) move across the membrane with help from proteins. |  | 14 |
| 8574236370 | Channel protein | This component of the cell membrane allows the transport of specific substances across a cell membrane. |  | 15 |
| 8574236371 | Passive transport | When substances move across the membrane without using extra energy (naturally happens). |  | 16 |
| 8574236372 | Active transport | Movement of substances across the cell membrane that require extra energy. |  | 17 |
| 8574236373 | Sodium- Potassium pump | a protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell |  | 18 |
| 8574236374 | Hypertonic solution | The type of solution that causes water molecules to leave the cell, and cell shrivels up and dies. |  | 19 |
| 8574236375 | Hypotonic solution | The type of solution that causes water molecules to move into the cell and the cell swells |  | 20 |
| 8574236376 | Isotonic solution | The type of solution when the same amount of water molecules enter and leave the cell. |  | 21 |
| 8574253011 | Aquaporin | The protein channel that allows water to pass through the membrane | 22 | |
| 8574292984 | Endocytosis | cell forming a vesicle around food or water |  | 23 |
| 8574300447 | Pinocytosis | Cell bringing in fluid into the cell |  | 24 |
| 8574314339 | Phagocytosis | Cell bringing in solids into the cells |  | 25 |
| 8574320563 | Exocytosis | vesicle bonds with cell membranes and releases contents to outside the cell |  | 26 |
