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 |
