Cellular Transport

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
