What will occur if a cell with osmotic pressure of 4500 mmHg is placed in a solution with 3500 mmHg?

When a cell with an osmotic pressure of 4500 mmHg is placed in a solution with an osmotic pressure of 3500 mmHg, the water will move out of the cell. This happens because the cell has a higher osmotic pressure than the surrounding solution, creating a gradient that leads to water diffusing towards the area of lower osmotic pressure.

As the water leaves the cell, the cell shrinks and loses volume, which corresponds with a decrease in pressure within the cell. This process is driven by osmosis, where water moves across a semipermeable membrane to equilibrate solute concentrations on both sides of the membrane. The result is that the cell loses water, leading to a decrease in internal pressure.

This understanding is important in the context of cellular biology, as it explains how cells react to different osmotic environments and the consequences of their placement in solutions with varying osmotic pressures.
