1. Water Movement in Plant Cells:

* Scenario: Plant cells are surrounded by a cell membrane that is selectively permeable, allowing water to pass through but not all other substances. When a plant cell is placed in a hypotonic solution (solution with lower solute concentration than inside the cell), water moves into the cell by osmosis.

* Outcome: This movement of water causes the cell to swell and become turgid, which is essential for the plant's structural support and rigidity.

2. Rehydration of the Body:

* Scenario: When you drink water after being dehydrated, the water in your digestive system has a lower concentration of dissolved substances (like salts) than the fluid inside your cells.

* Outcome: Water moves into the cells by osmosis, restoring the balance of fluids and rehydrating your body. This is why drinking water is crucial for maintaining proper cell function and overall health.
