Two cells A and B are contiguous. Cell A has osmotic pressure 10 atm, turgor pressure-7 atm and diffusion pressure deficit 3 atm. Cell B has osmotic pressure 8 atm, turgor pressure 3 atm and diffusion pressure deficit 5 atm. The result will be

Options

A. movement of water from cell B-A
B. no movement of water
C. equilibrium between the two
D. movement fo water from cell A-B

Explanation

To solve the problem regarding the movement of water between two contiguous cells A and B based on their osmotic pressure, turgor pressure, and diffusion pressure deficit (DPD), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- For Cell A:
- Osmotic Pressure (OP_A) = 10 atm
- Turgor Pressure (TP_A) = 7 atm
- DPD_A = OP_A - TP_A = 10 atm - 7 atm = 3 atm
- For Cell B:
- Osmotic Pressure (OP_B) = 8 atm
- Turgor Pressure (TP_B) = 3 atm
- DPD_B = OP_B - TP_B = 8 atm - 3 atm = 5 atm

2. **Calculate the Diffusion Pressure Deficit (DPD) for Both Cells:**
- DPD for Cell A: DPD_A = 3 atm
- DPD for Cell B: DPD_B = 5 atm

3. **Determine the Direction of Water Movement:**
- Water moves from a region of lower DPD to a region of higher DPD.
- Since DPD_A (3 atm) < DPD_B (5 atm), water will move from Cell A to Cell B.

4. **Conclusion:**
- The result of the analysis indicates that water will flow from Cell A to Cell B due to the difference in diffusion pressure deficit.

### Final Answer:
Water will move from Cell A to Cell B.
