| Active Transport | The process of materials moving across a membrane using energy. |
| Diffusion | When small molecules spread out. |
| Dynamic Equilibrium | When materials are equal on both sides of the membrane. |
| Endocytosis | When the membrane pinches in to let marterials enter the cell. |
| Exocytosis | When materials exit the cell. |
| Facilitated Diffusion | When materials move across the membrane with the help of a protein. |
| Hypertonic Solution | When there is more water inside the cell. |
| Hypotonic Solution | When there is more water outside the cell. |
| Isotonic Solution | When there is the same amount of water on the inside and outside of the cell. |
| Osmosis | The process of water moving across a membrane. |
