OSMOSIS is the movement of water through a semi-permeable membrane.
What is TONICITY?
TONICITY is the study of water and solute. It is also the ability of the solution to lose or gain water.
Types of Tonicity in Cells
- Isotonic solution is the solution in which the amount of solute and solvent are equal. Animal cells that are submerged into an isotonic solution is normal while a plant cell will be flaccid or soft and hanging loosely.
- Hypertonic solution is the solution wherein there is more solute than solvent. Animal cells in this solution tends to shrink and plant cells will undergo plasmolysis and will be plasmolyzed.
- Hypotonic solution is the solution in which there are more solvent than solute. Animal cells that are exposed to this solution will undergo lysis and will be lysed while a plant cell will be in its normal state. The reason why plants will be in normal in a hypotonic solution is because plants need more water.
