A cell is placed in a hypertonic solution. What will happen to it?
When a cell is placed in a hypertonic solution, it loses water and shrinks because water moves out of the cell.
Key Concept
| Term | Meaning |
|---|---|
| Hypertonic Solution | Solution with higher solute concentration than the cell |
| Osmosis | Movement of water from low solute to high solute concentration |
Key Effects
| Effect | Impact | Explanation |
|---|---|---|
| Water Loss | Cell shrinks | Water moves out to balance concentration |
| Cell Shape Change | Becomes shrunken | Plasma membrane pulls inward |
| Plant Cell | Plasmolysis | Cell membrane separates from cell wall |
| Animal Cell | Shrinkage | No cell wall, so it just shrinks |
Stepwise Understanding
Cell is placed in hypertonic solution
Outside solution has more solute than inside
Water moves out of the cell through osmosis
Cell starts losing volume
Cell shrinks
Important Concept
Water always moves from lower solute concentration to higher solute concentration.
Real Insight
In plant cells, this condition causes plasmolysis, where the cell membrane detaches from the wall, which can damage the cell if prolonged.
So overall, hypertonic solution causes water loss and shrinkage of the cell.
