As a result of endosmosis , `Psi_(W)` of cell

Options

A. Increase
B. Decrease
C. Remain same
D. Become zero

Answer

### Step-by-Step Solution:

1. **Understanding Water Potential (Ψw)**:
- Water potential (Ψw) is a measure of the potential energy of water in a system and is influenced by solute concentration and pressure. In pure water, the water potential is at its maximum (0 MPa).

2. **Concept of Endosmosis**:
- Endosmosis refers to the movement of water into a cell when it is placed in a hypotonic solution (a solution with a lower concentration of solutes compared to the inside of the cell).

3. **Hypotonic Solution**:
- When a cell is placed in a hypotonic solution, water moves into the cell due to osmosis. This is because the concentration of solutes is higher inside the cell than outside, creating a gradient that favors water influx.

4. **Effect on Water Potential**:
- As water enters the cell, the solute concentration inside the cell increases, which can lead to an increase in the water potential (Ψw) of the cell. This is because the water potential is influenced by both solute potential and pressure potential.

5. **Conclusion**:
- Therefore, as a result of endosmosis, the water potential (Ψw) of the cell increases due to the influx of water, which dilutes the solute concentration inside the cell.
