A cell placed in a solution get deplasmolysed . The solution is

Options

A. Hypotonic
B. Hypertonic
C. Isotonic
D. Ditonic

Answer

To determine the type of solution in which a cell gets deplasmolyzed, we need to understand the concepts of plasmolysis and deplasmolysis.

### Step-by-Step Solution:

1. **Understanding Plasmolysis**:
- Plasmolysis occurs when a cell is placed in a hypertonic solution, causing water to move out of the cell. This leads to the shrinkage of the protoplasm away from the cell wall.

2. **Understanding Deplasmolysis**:
- Deplasmolysis is the process where the protoplasm of a cell returns to its normal state after being plasmolyzed. This happens when the cell is placed in a solution that allows water to enter the cell.

3. **Types of Solutions**:
- **Hypotonic Solution**: Has a lower concentration of solutes compared to the inside of the cell. Water moves into the cell, causing it to swell and become turgid.
- **Isotonic Solution**: Has the same concentration of solutes as the inside of the cell. There is no net movement of water, and the cell remains the same size.
- **Hypertonic Solution**: Has a higher concentration of solutes compared to the inside of the cell. Water moves out of the cell, causing it to shrink.
- **Diatonic Solution**: This term is not recognized in biological contexts.

4. **Conclusion**:
- Since the question states that the cell gets deplasmolyzed, it indicates that the cell was previously plasmolyzed. This can only happen if the cell is placed in a hypotonic solution, which allows water to enter the cell and restore its turgidity.

### Final Answer:
The solution is **hypotonic**.
