What is the direction of the movement of water if two cells have the same OP but differ in TP ?

Options

A. No net flow
B. From lower T.P to higher TP
C. From higher TP to lower TP
D. DPD = 0 atm., OP = 15 atm., TP = 15 atm.

Answer

To determine the direction of water movement between two cells with the same osmotic pressure (OP) but different turgor pressure (TP), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Osmotic Pressure (OP)**: The pressure required to prevent the flow of water across a semipermeable membrane due to osmosis.
- **Turgor Pressure (TP)**: The pressure exerted by the fluid (usually water) inside the cell against the cell wall. It is a measure of the cell's internal pressure.

2. **Identify Given Conditions**:
- We have two cells, Cell 1 and Cell 2.
- Both cells have the same osmotic pressure (OP).
- The turgor pressures are different (let's say TP of Cell 1 is higher than TP of Cell 2).

3. **Determine Water Movement Direction**:
- Water moves from areas of higher turgor pressure to areas of lower turgor pressure.
- Since Cell 1 has a higher turgor pressure than Cell 2, water will move from Cell 1 to Cell 2.

4. **Conclusion**:
- The direction of water movement will be from Cell 1 (high turgor pressure) to Cell 2 (low turgor pressure).

### Final Answer:
Water will move from Cell 1 to Cell 2.
