The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Water Movement**: Water moves into the plant cell from the surrounding environment primarily through the process of osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. 2. **Hydrostatic Pressure (Ψp)**: As water enters the cell, it creates hydrostatic pressure, which is the pressure exerted by the fluid (in this case, water) against the cell wall. This pressure is denoted as Ψp (psi p). 3. **Turgidity of the Cell**: The increase in hydrostatic pressure causes the plant cell to become turgid. Turgidity is a state where the cell is swollen and firm due to the pressure of the fluid inside against the cell wall. This is essential for maintaining the structural integrity of the plant. 4. **Increase in Pressure Potential**: The hydrostatic pressure (Ψp) contributes to the overall pressure potential of the cell. As the cell becomes turgid, the pressure potential increases. 5. **Effect on Water Potential (Ψw)**: The water potential (Ψw) of the cell is a measure of the potential energy of water in the system. As the pressure potential increases due to the influx of water and the resulting turgidity, the overall water potential of the cell also increases. 6. **Conclusion**: Therefore, as water moves into the cell, the hydrostatic pressure (Ψp) increases, resulting in the cell becoming turgid and increasing both the pressure potential and the water potential (Ψw) of the cell. **Final Statement**: As water moves into the cell from outside, the hydrostatic pressure (Ψp) increases, resulting in the cell becoming turgid and an increase in the water potential (Ψw) of the cell. ---
