|---|
| diffusion | movement of molecules from high to low concentration |
| osmosis | movement of water from high to low concentration across a membrane |
| Kinetic Molecular Theory | all molecules are in constant random motion |
| permeable | membrane that allows a substance to pass through |
| impermeable | membrane that does NOT allow a substance to pass through |
| semipermeable | selectively permeable |
| net movement | more molecules move in one direction than in the opposite direction |
| dynamic equilibrium | same number of molecules moving in each direction |
| isotonic | same amount of solutes inside and outside the cell |
| hypotonic | water will move OUT of this type of solution |
| hypertonic | water will move INTO this type of solution |
| solutes | the particles in a solution |
| solvent | the liquid in a solution |
| homeostasis | maintaining the same internal environment |
