| A | B |
| Solution | The mixture of two or more substances |
| Solvent | A substance that is dissolving another substance. (water) |
| Solute | A substance that is being dissolved. (sugar) |
| Concentration | The amount of a substance being dissolved compared to the amount of substance that is doing the dissolving |
| Equilibrium | Where concentrations of particles are equal both inside and outside the cell |
| Diffusion | The movement of particles from areas of high concentration to areas of low concentration |
| Osmosis | the movement of water from areas of high concentration to areas of low concentration |
| Selectively Permeable | The characteristic of a membrane that allows certain substances in and out but not all substances |
| Passive Transport | The movement of molecules without the need of energy |
| Hypertoic Solution | a cell with more water inside the cell than out and will lose, shrink or shrivel, water due to equilibrium |
| Hypotonic | A cell with less water inside the cell than out and will absorb water, swell, due to equilibrium |
| Isotonic | A cell that has equal concentrations of water inside and outside the cell |
| Active Transport | The movement of molecules with the need of energy |
