Explain: Plasmolysis is the process by which a plant cell loses water through hypertonic solutions.
Plasmolysis is the process that takes place when the plant cell loses cytoplasmic water due to osmosis and shrinks in size.
Plasmolysis is the process of shrinkage or contraction of the cell contents away from the cell wall when a living plant cell loses water through osmosis. The process of plasmolysis does not occur in dead cells.
It occurs when the plant's cell is placed in a hypertonic solution or solution having a higher concentration of salts. Cytoplasm loses its water to the hypertonic solution to achieve equilibrium and shrinks.
[Extra information:
1. When the animal cell is placed in a hypotonic solution (A solution that contains less solute compared to the animal cell), endo-osmosis takes place. The water moves inside the animal cell, thus the cell swells and bursts.
2. When the animal cell is placed in an isotonic solution (Solution having the same concentration of solute as in the cell), no water movement occurs, thus the cell shape will remain unchanged.
3. When the animal cell is placed in a hypertonic solution (A solution having a higher concentration of solute compared to the animal cell), ex-osmosis occurs. The water comes out of the animal cell, and the cell shrinks and dies.]
