The magnitude of following quantities increases when water starts entering into the cell

Options

A. Water potential
B. Turgor pressure
C. Osmotic potential
D. 1 and 2

Answer

To solve the question regarding which quantities increase when water enters a cell, we can break down the concepts involved step by step:

### Step-by-Step Solution:

1. **Understanding Water Entry into Cells**:
- When water enters a cell, it causes the cell to swell and become turgid. This is due to the movement of water from an area of higher water potential (outside the cell) to an area of lower water potential (inside the cell).

2. **Identifying Key Terms**:
- **Water Potential**: This is the potential energy of water in a system compared to pure water, and it influences the movement of water. When water enters the cell, the water potential inside the cell increases.
- **Turgor Pressure**: This is the pressure exerted by the fluid (water) inside the cell against the cell wall. As water enters the cell, turgor pressure increases, making the cell firm and turgid.
- **Osmotic Potential**: This refers to the potential of water to move into a cell via osmosis, which is influenced by the concentration of solutes. When water enters the cell, the concentration of solutes remains the same, but the overall osmotic potential does not increase; it may actually decrease due to dilution.

3. **Analyzing Each Quantity**:
- **Water Potential**: Increases when water enters the cell because the concentration of water increases.
- **Turgor Pressure**: Increases as the cell becomes turgid due to the influx of water.
- **Osmotic Potential**: Does not increase; it may decrease because the solute concentration is diluted by the incoming water.

4. **Conclusion**:
- The quantities that increase when water enters the cell are **Water Potential** and **Turgor Pressure**.

### Final Answer:
- The quantities that increase when water starts entering into the cell are **Water Potential** and **Turgor Pressure**.
