| Passive Transport | The movement of substances through the cell membrane without the input of energy. |
| Diffusion | A type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them. |
| equilibrium | Moleules of a substance will continue to move from one area into another until the relative number of these molecules is equal in the two areas. |
| osmosis | The diffusion of water through a cell membrane |
| Active Transport | When an input of energy is required to move materials through a cell membrane. |
| Endocytosis | taking substances into the cell by surrounding it with the cell membrane |
| Selectively Permeable Membrane | Allows some things to enter the cell and others not to enter. |
| Solutes | A substance that dissolves in a solvent |
| Solvent | Will dissolve a solute, ex:water |
| Hypertonic | Higher concentration of solutes |
| Hyptonic | lower concentration of solutes. water moves to higher solute concentrations. |
| Isotonic | equal concentration of solutes |
| Facilitated Diffusion | some molecules are so large that the need help getting through the cell membrane |
| Transport Protein | attaches to the molecule, moves through cell membrane, unattach and go to get another molecule |
| Active Transport | Input of energy is required to move substances through a cell membrane |
| vesicle | sphere made when the cell membrane folds in on inself |
| endocytosis | taking substances into the cell by surrounding it with cell membrane |
| exocytosis | moves big items out of cell vessicle fuses with cell membrane and opens up to expel items |
