explain the effect of istonic, hypotonic and hypertonic solution on a cell
Answers
Explanation:
Isotonic: Plant cells exposed to isotonicconditions will lose turgor pressure and become flaccid. ... In biology, the solutions on either side of a cellmembrane are isotonic if the concentration of solutes outside thecell is equal to the concentration of solutes inside the cell.
Hypotonic: When the plant cell is placed in ahypotonic solution , it takes up water by osmosis and starts to swell, but thecell wall prevents it from bursting. Theplant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
Hypertonic: If a plant cell is placed in a hypertonicsolution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cellshrink and crumple.
