| Term | Definition |
| Fluid Mosaic Model | Has a double bilayer of lipids with imbedded, dispersed proteins. |
| Bilayer | Consists of pospholipids, cholesterol, and glycolipids. |
| Glycolipids | These are lipids bounds with a carbohydrate. |
| Tight, Desmosome, Gap | Three juctions that bind cells together. |
| Tight | The juction that is impermeable meaning it has tight interlocking proteins. |
| Desmosome | This junction has anchors along side of a cell. |
| gap | This juction has a channel to allow substance to pass from cell to cell without going to the outside. |
| Simple diffusion, Facilitated diffusion, Osmosis | Three types of Passive membrane transport. |
| Simple diffusion | The passive membrane transport that is easy through the membrane. The particles go from an area of high concentration to an area of less concentration. |
| Facilitated diffusion | The passive membrane transport when a substance binds to or is transported by carrier proteins. |
| Gases | Simple diffusion transports what? |
| Glucose, aminos, ions | Facilitated diffusion transports what? |
| Osmosis | The passive membrane transport that moves water from an area of high concentration to an area of low. |
| Osmosis | This transport occurs when the concentration of a solvent is different on opposite sides of a membrane. |
| Isotonic | This is a solution that has the same solute concentration as cytosol (a cell). |
| Hypertonic | These are solutions that have greater solute than cytosol. |
| Hypotonic | These are solutions that have less solute than cytosol. |
| Hypertonic | When a cell has too much sodium on the outside and little on the inside the cell dehydrates. |
| Hypotonic | When a cell has too much sodium on the inside and little on the outside the cell is bloated. |
