Cell Transport
| Term | Definition |
|---|---|
| Osmosis | The movement of water from an area of high concentration to low. |
| Diffusion | The movement of particles from an area of high concentration to low. |
| Hypertonic | Concentration of dissolved substances is higher on the outside of the cell. |
| Hypotonic | Concentration of dissolved substances is lower on the outside of the cell. |
| Isotonic | Concentration of dissolved substances is the same on the inside and outside of the cell. |
| Passive Transport | The movements of materials across the cell membrane without the use of energy. |
| Active Transport | The movement of materials across the cell membrane with the use of energy. |
| Facilitated Diffusion | The movement of materials from an area of higher concentration to an area of lower concentration with the help of transport proteins. |
| Endocytosis | Active transport, engulfing material into the cell. |
| Exocytosis | Active transport of materials out of the cell. |
| Equilibrium | Continuous movement of particles but no overall change in concentration of materials |
| Semi-Permeable | Allows some substances in and out of the cell but not others. |
| Solvent | Substance in which another substance is dissolved |
| Solute | Substance dissolved in a solvent |
| Fluid Mosaic | Model that describes the plasma membrane. Fluid because proteins can move within the layer and mosaic because of the pattern it makes |
