WebTonicity is a measure of the relative concentration of solute particles on either side of a semi-permeable membrane (e.g. inside a cell versus outside the cell). Only solutes that cannot cross the membrane contribute to tonicity. It determines the direction and extent to which water moves by osmosis. The higher the tonicity the greater the ... WebHow does tonicity affect pressure in a cell? A common solvent would be water. That solute can exert a certain amount of pressure referred to as tonicity. This pressure can affect … WebIf a cell is put into a hypertonic solution, water will leave the cell. A quick tip to remembering this is to visualize “hyper” kids who want to go play outside!
