What is expected to happen when a cell with a selectively permeable membrane is placed in water after being filled with glucose?

When a cell with a selectively permeable membrane is placed in water after being filled with glucose, water is expected to move into the cell. This is due to the concentration gradient created by the presence of glucose inside the cell.

Glucose is a solute, and if the concentration of glucose inside the cell is higher than the concentration of solutes in the surrounding water (assuming the water is pure or has a lower concentration of solutes), water will move into the cell through osmosis. Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration (in this case, the surrounding water) to an area of higher solute concentration (inside the cell, where glucose is present).

This movement continues until an equilibrium is reached or until the cell reaches a point where it can no longer take in more water without bursting. Hence, placing the glucose-filled cell in water triggers the influx of water into the cell, emphasizing the fundamental principle of osmosis and the behavior of cells in response to different solute concentrations.
