Study Notes
Isotonic Solutions
- Maintains equal osmotic concentration with a cell's cytoplasm.
- Neither shrinks nor swells the cell; it remains in equilibrium.
- Ideal for maintaining cell shape and function in physiological conditions.
Hypertonic Solutions
- Causes cells to shrivel due to water loss.
- Water moves out of a cell toward the area of higher solute concentration.
- Can lead to plasmolysis in plant cells and crenation in animal cells.
Hypotonic Solutions
- Causes cells to swell as water enters them.
- There is a higher concentration of water outside the cell than inside.
- Can result in lysis of animal cells and turgor pressure in plant cells.
