Cell A with OP = 6 and WP = 5 is surrounded by the cells with OP = 3 and TP = 2 , what will be the direction of water movement ?

Options

A. From A to other cells
B. From other cells to A
C. No movement
D. Water will move up

Answer

To determine the direction of water movement between cell A and the surrounding cells, we need to analyze the osmotic pressure (OP), turgor pressure (TP), and the resulting water potential.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- For Cell A:
- Osmotic Pressure (OP) = 6
- Turgor Pressure (TP) = 5
- For Surrounding Cells:
- Osmotic Pressure (OP) = 3
- Turgor Pressure (TP) = 2

2. **Calculate the Diffusion Pressure Deficit (DPD):**
- DPD is calculated using the formula:
\[ \text{DPD} = \text{OP} - \text{TP} \]
- For Cell A:
\[ \text{DPD}_A = \text{OP}_A - \text{TP}_A = 6 - 5 = 1 \]
- For the surrounding cells:
\[ \text{DPD}_{\text{surrounding}} = \text{OP}_{\text{surrounding}} - \text{TP}_{\text{surrounding}} = 3 - 2 = 1 \]

3. **Compare the DPD Values:**
- DPD for Cell A = 1
- DPD for Surrounding Cells = 1

4. **Determine Water Movement:**
- Water moves from areas of lower DPD to areas of higher DPD. Since both Cell A and the surrounding cells have the same DPD value (1), there will be no net movement of water between them.

5. **Conclusion:**
- The direction of water movement is **no movement**.

### Final Answer:
The answer to the question is option C: **no movement**.
