A cell will absorb water and show deplasmolysis when it is immersed in

Options

A. isotonic solution
B. hypertonic solution
C. hypotonic solution
D. any of the above

Answer

To solve the question, "A cell will absorb water and show deplasmolysis when it is immersed in," we need to understand the concepts of plasmolysis, deplasmolysis, and the types of solutions: isotonic, hypertonic, and hypotonic.

### Step-by-Step Solution:

1. **Define Plasmolysis and Deplasmolysis**:
- **Plasmolysis** is the process where a cell loses water and shrinks due to being in a hypertonic solution (where the concentration of solutes outside the cell is higher than inside).
- **Deplasmolysis** is the opposite process, where a cell absorbs water and swells back to its normal state after being in a hypertonic solution.

2. **Understand the Types of Solutions**:
- **Isotonic Solution**: The concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
- **Hypertonic Solution**: The concentration of solutes is higher outside the cell, causing water to move out of the cell, leading to plasmolysis (shrinkage).
- **Hypotonic Solution**: The concentration of solutes is lower outside the cell, causing water to move into the cell, leading to deplasmolysis (swelling).

3. **Identify the Correct Solution for Deplasmolysis**:
- Since deplasmolysis occurs when a cell absorbs water, it must be in a hypotonic solution. In this type of solution, water moves into the cell, causing it to swell and return to its normal state.

4. **Conclusion**:
- Therefore, the correct answer to the question is that a cell will absorb water and show deplasmolysis when it is immersed in a **hypotonic solution**.

### Final Answer:
A cell will absorb water and show deplasmolysis when it is immersed in a **hypotonic solution**.
