Study Notes
Osmosis Overview
- Osmosis is the process of water diffusion through a selectively permeable membrane.
- Water moves from an area of low solute concentration to an area of high solute concentration until equilibrium is reached.
Key Concepts of Tonicity
-
Tonicity refers to the effect of surrounding solutions on a cell's water balance.
-
Isotonic Solution:
- Solute concentration is equal to that of the cell.
- No net movement of water occurs.
-
Hypertonic Solution:
- Solute concentration is greater than that of the cell.
- Causes the cell to lose water, resulting in cell shrinkage.
-
Hypotonic Solution:
- Solute concentration is lower than that of the cell.
- Leads to water entering the cell, potentially causing it to swell or burst.
