What is plasmolysis and deplasmolysis?

Plasmolysis

1. It refers to the shrinking and seperation of the cell membrane from the cell wall due to exosmosis.

2. Water Molecules move out of the cell.

3. Occurs during exosmosis.

4. Occurs when cell are placed in a "Hypertonic solution".

5. Occurs when the solute concentration of the Surrounding solution is higher than that of the Cytoplasm.

6. Occurs when the water potential of the surrounding solution is less than that of cytoplasm

7. The Cells may Shrink.

8. Osmotic Pressure of the cell is very Low.

Deplasmolysis

1. It refers to the entrance of water into a plasmolysed plant cell, causing the cell membrane to return to the cell wall.

2. Water Molecules move into of the cell.

3. Occurs during Endosmosis.

4. Occurs when cells are placed in a Hypotonic Solution.

5. Occurs when the solute concentration of the surrounding solution is less than that of cytoplasm.

6. Occurs when the water potential of the surrounding solution is higher than that of cytoplasm.

7. The cells may Swell.

8. Osmotic Pressure of the Cell wall is very High.

Plasmolysis is the process of water leaving plant cells, allowing the cytoplasm and plasma membrane to shrink away from the cell wall. This causes plants to wilt. Indeplasmolysis, water from the outside environment rushes into the cell through a process called osmosis, which creates turgor pressure.

Plasmolysis occurs when a cell is placed in a hypertonic solution. In other words when a cell is placed in a surrounding environment where the concentration of solute particles is higher thereby causing water from the cell to flow out this is termed Plasmolysis. What happens is that the cell shrinks in size losing it's tonic it due to water escaping. Now if this cell is again placed in a new medium which now is hypotonic to its inner environment as in the surrounding medium has lower solute count then water will rush in filling up the cell causing it to swell this is called Deplasmolysis. Place a potato in the salt solution and see.

In deplasmolysis, water from the outside environment rushes into the cell through a process called osmosis, which creates turgor pressure

When a cell is placed in a hyperonic solution, enxosmosis takes place through the cell wall of plant resilting in cytoplasm shrinkage. This phenomenon is called plasmolysis

Deplasmolysis is the reverse of plasmolysis i.e.when cell placed in hypotonic solution, endosmosis takes place resulting in cell to be turgid.
