Movement of water across a semi-permeable membrane in response to the difference in the electrochemical potential in water Osmosis
Movement of water is driven by a difference in solute concentrations on the two sides of the membrane Osmosis
Water flows from the solution with lower solute concentration into the solution with higher solute concentration Osmosis
Pressure generated when water diffuses across the cell membrane Osmotic pressure
Pressure required in stopping osmosis completely Osmotic pressure
Formula for Osmotic Pressure van Hoff's Law
Osmolarity of a solution relative to plasma Tonicity
Osmolarity of plasma 0.3 osm/L or 300 mosm/L
