Plasmolysis is due to

Options

A. Exosmosis
B. Endosmosis
C. Osmosis
D. Adsorptioin

Answer

**Step-by-Step Text Solution:**

1. **Understanding Plasmolysis**: Plasmolysis is a process that occurs in plant cells when they lose water. This typically happens when the cells are placed in a hypertonic solution, which has a higher concentration of solutes compared to the inside of the cell.

2. **Identifying the Cause**: When a plant cell is placed in a hypertonic solution, water moves out of the cell into the surrounding solution. This movement of water is due to osmosis, which is the process of water moving from an area of lower solute concentration to an area of higher solute concentration.

3. **Defining Exosmosis**: The specific type of osmosis that occurs when water moves out of the cell is called exosmosis. In this case, the cell loses water, causing it to shrink and become flaccid.

4. **Differentiating from Other Processes**:
- Endosmosis is the opposite process, where water moves into the cell from the outside, causing the cell to swell.
- Osmosis is a general term for the movement of water across a semi-permeable membrane, but it does not specify the direction of water movement.
- Absorption refers to the uptake of substances, which is not the same as the process of water movement that leads to plasmolysis.

5. **Conclusion**: Therefore, plasmolysis is specifically due to exosmosis, as it involves the loss of water from the plant cell into a hypertonic solution.

**Final Answer**: Plasmolysis is due to exosmosis.
