Osmosis:The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.
Isotonic: A condition where the concentrations of solutes outside and inside the cell are equal, resulting in no net movement of water across the cell membrane.
Hypertonic: A solution where the concentration of solutes outside the cell is higher than that inside, causing water to move out of the cell and potentially leading to cell shrinkage
