When strong salt solution plasmolyses a cell, then the space between cell wall and plasma membrane is filled with

Options

A. Water
B. Salt solution
C. Cell sap
D. Protoplasm

Explanation

**Step-by-Step Solution:**

1. **Understanding Plasmolysis**:
- Plasmolysis is the process where the protoplast (the living part of the cell, including the plasma membrane and cytoplasm) of a plant cell shrinks away from the cell wall. This occurs when the cell loses water due to osmotic pressure.

2. **Cause of Plasmolysis**:
- The primary reason for plasmolysis is the presence of a hypertonic solution (in this case, a strong salt solution) outside the cell. The water inside the cell moves out to balance the concentration of solutes, leading to the shrinkage of the protoplast.

3. **Space Between Cell Wall and Plasma Membrane**:
- When plasmolysis occurs, the space that forms between the cell wall and the plasma membrane is filled with the external solution. Since the external solution is a strong salt solution, this space will be filled with that salt solution.

4. **Conclusion**:
- Therefore, when a strong salt solution plasmolyzes a cell, the space between the cell wall and the plasma membrane is filled with the salt solution.

**Final Answer**: The space between the cell wall and the plasma membrane is filled with the salt solution.
