- Plasmolysis is a scientific term used for the above change.
Plasmolysis occurs due to shrinkage of protoplasm when a plant cell is
kept in a hypertonic medium and water flows out from a cell.
- To restore the cell back to its original condition, it must be placed in a
hypotonic solution immediately after it gets plasmolyzed.
- Deplasmolysis is a scientific term used for the recovery of the cell as a
result of the step taken above.
- Osmosis: It is the movement of water molecules from the region of its
lower concentration to the region of higher concentration through a
semipermeable membrane.
