Osmotic potential is numerically equal to

Options

A. Turgor pressure
B. Wall pressure
C. Osmotic pressure
D. D.PD.

Answer

**Step-by-Step Solution:**

1. **Understanding Osmotic Potential**: Osmotic potential is a measure of the tendency of water to move into a solution due to the presence of solute particles. It is a key concept in understanding how water moves in and out of plant cells.

2. **Movement of Water**: Water movement in plants occurs due to osmotic potential gradients. Water moves from areas of high osmotic potential (low solute concentration) to areas of low osmotic potential (high solute concentration).

3. **Osmotic Potential and Osmotic Pressure**: Osmotic potential is numerically equal to osmotic pressure. Osmotic pressure is the pressure required to stop the flow of water across a semipermeable membrane due to osmosis.

4. **Eliminating Incorrect Options**:
- Turgor Pressure: This is the pressure exerted by the fluid inside the cell against the cell wall, which is not equal to osmotic potential.
- Wall Pressure: This is the pressure exerted by the cell wall on the contents of the cell, which is also not equal to osmotic potential.
- Diffusion Pressure Deficit (DPD): This is the difference between osmotic pressure and turgor pressure, and it is not equal to osmotic potential.

5. **Conclusion**: Therefore, the correct answer to the question "Osmotic potential is numerically equal to" is osmotic pressure.

**Final Answer**: Osmotic potential is numerically equal to osmotic pressure.
