WebTonicity is defined as the ability of a solution which surrounds the cell to cause the cell to gain or lose water. It depends on the relative concentration of solutes across a cell membrane which determines the direction and extent of osmotic flux. Three terms are used to determine tonicity- hypertonic, hypotonic, isotonic. WebOsmotic pressure is the pressure required to stop water from diffusing through a membrane by osmosis. It is determined by the concentration of the solute. Water diffuses into the area of higher concentration from the … how does society perceive media
