Study Notes
Osmosis
- Osmosis is the movement of water across a semi-permeable membrane, selectively allowing only certain molecules to pass through.
- Water is usually the only free-flowing molecule across this membrane.
Types of Solutions
- Isotonic Solutions: have the same solute and pH concentration as the surrounding body fluid or cytoplasm.
- Hypotonic Solutions: contain a lesser amount of solute concentration compared to the surrounding fluid, causing cells to rupture due to excess water input.
- Hypertonic Solutions: contain a higher concentration of solute compared to the surrounding fluid, pushing water out of cells and causing them to shrink.
