Under natural conditions the osmotic pressure is

Options

A. More than turgor pressure
B. Less than turgor pressure
C. Equal to turgor pressure
D. Zero

Answer

To answer the question "Under natural conditions, the osmotic pressure is?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Osmotic Pressure**:
- Osmotic pressure is defined as the minimum pressure required to prevent the flow of water across a semi-permeable membrane. It is the pressure that must be applied to a solution to prevent the inward flow of water.

2. **Comparison with Turgor Pressure**:
- Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole against the cell wall. It is responsible for maintaining the structure and rigidity of plant cells.

3. **Analyzing the Relationship**:
- In a plant cell, osmotic pressure is typically higher than turgor pressure. This is because osmotic pressure is generated by the solutes present in the cell, which draw water in, while turgor pressure is the result of this water pushing against the cell wall.

4. **Conclusion**:
- Therefore, under natural conditions, osmotic pressure is greater than turgor pressure. The correct answer to the question is that osmotic pressure is more than turgor pressure.

### Final Answer:
- Under natural conditions, the osmotic pressure is **more than turgor pressure**.
