| 8427518917 | Plasma membrane (cell membrane) | Regulates what enters and leaves the cell and separates the internal environment of the cell from the external environment |  | 0 |
| 8427518918 | 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 |
| 8427518919 | Selectively permeable | The term to describe a cell membrane that allows some substances to pass, but not others |  | 2 |
| 8427518920 | Bilayer | The cell membrane is made of two layers of lipid molecules. |  | 3 |
| 8427518921 | Phospholipid | Makes up the cell membrane; has 1 head (hydrophilic) and 2 tails (hydrophobic) | | 4 |
| 8427518922 | Polar Head | part of the phospholipid that is attracted to water. |  | 5 |
| 8427518923 | Non-Polar Tail | Part of the phospholipid that is not attracted to water. |  | 6 |
| 8427518924 | Hydrophilic | Means "water lovings" Describes the heads (circle portion) of the phospholipids | | 7 |
| 8427518925 | Hydrophobic | Means water fearing. Describes the tails of the phospholipids | | 8 |
| 8427518927 | Marker Protein | This component of the cell membrane allows different cells in your body to identify each other. | 9 | |
| 8427518932 | Channel protein | This component of the cell membrane allows the transport of specific substances across a cell membrane. |  | 10 |
| 8427527582 | Cholesterol | This component of the cell membrane provides stability and flexibility for the structure. | 11 | |
| 8427535432 | Extracellular fluid and cytoplasm | This region around the cell membrane contains water. | 12 |
