Explanation:

The given scenario describes a cell (A) with a higher osmotic pressure (O. P) surrounded by cells with lower osmotic pressure (O. P=3 and T. P=2) and the direction of water movement.

1. Osmosis:

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration across a semi-permeable membrane. In this case, the semi-permeable membrane is the cell membrane.

2. Osmotic Pressure:

Osmotic pressure is the pressure required to prevent the movement of water across a semi-permeable membrane due to differences in solute concentration. It is directly proportional to the concentration of solutes in a solution.

3. Higher Osmotic Pressure:

In this scenario, cell A has a higher osmotic pressure (O. P=6) compared to the surrounding cells with lower osmotic pressure (O. P=3 and T. P=2). This means that cell A has a higher concentration of solutes than the surrounding cells.

4. Water Movement:

As per the principle of osmosis, water moves from an area of high concentration to an area of low concentration. However, in this scenario, the surrounding cells have a lower concentration of solutes compared to cell A. Hence, there is no concentration gradient for water to move from cell A to the surrounding cells.

5. No Movement:

Therefore, in this scenario, there is no movement of water from cell A to the surrounding cells. The water remains in its position, and there is no change in the volume of any of the cells.

Conclusion:

The direction of water movement across a semi-permeable membrane depends on the concentration of solutes on both sides of the membrane. When there is no concentration gradient, as in this scenario, there is no movement of water.

According to NCERT DPD=OP - TP in first cell wp=5 hence TP= 5 thusfor 1st cell DPD=6-5=1 for 2nd cell DPD=3-2=1DPD in both case same hence no water movement
