Osmosis
| Term | Definition |
|---|---|
| cell membrane | maintains what goes in and out of cel l |
| homeostasis | "steady" balance |
| diffusion | the movement of particles from high to low concentrations |
| osmosis | the movement of water from high to low concentrations |
| hypotonic | solution in which the cell swells, concentration is greater inside the cell |
| isotonic | solution in which the concentrations are equal |
| hypertonic | solution which causes the cell to shrink, concentration is greater outside the cell |
| passive transport | movement of particles from high to low, no energy is required for movement |
| active transport | particles move from low to high, energy is needed for movement |
| solution | when the solute and solvent are dissolved together |
| solute | any chemical dissolved in water |
| solvent | dissolving chemical |
| facilitated diffusion | protein is required to move particles but requires no energy |
| ATP | energy molecule |
