Study Notes

Solutions in Osmosis

Hypotonic Solution: Has a lower solute concentration than the inside of the cell, leading to water entering the cell.
Cell Swelling: Cells placed in a hypotonic solution swell due to osmotic pressure.

Isotonic Solution

Equal Concentration: Solute concentration is the same both inside the cell and in the solution, resulting in no net movement of water.
Stability: Injection of isotonic solutions results in no cell disruption.

Hypertonic Solution

Higher Solute Concentration: This solution has a higher solute concentration than inside the cell, causing water to exit the cell.
Cell Shriveling: Cells placed in a hypertonic solution will shrivel as they lose water.
Plant Wilting: A plant in a hypertonic solution experiences water loss, leading to wilting.

Concentration Examples

Hypotonic Concentrations:
- 60% solute inside, 10% outside
- 25% solute inside, 20% outside
- 55% solute inside, 25% outside
- 40% solute inside, 30% outside
- 40% solute inside, 20% outside
Isotonic Concentrations:
- 50% solute inside, 50% outside
- 10% solute inside, 10% outside
Hypertonic Concentrations:
- 10% solute inside, 15% outside
- 18% solute inside, 75% outside
- 43% solute inside, 60% outside
- 10% solute inside, 20% outside (listed multiple times indicates multiple scenarios of hypertonicity).

Effects on Cells

Hypotonic: Cells swell as water enters.
Isotonic: No significant change in cell volume as water movement is balanced.
Hypertonic: Cells lose water, shrink, and may become plasmolyzed in plants.
