Study Notes
Solutions Overview
- Isotonic Solutions: Equal distribution of solute and solvent; concentration inside the cell matches outside, maintaining cellular equilibrium.
- Hypotonic Solutions: Higher solute concentration compared to solvent; example includes a solution with a lot of salt dissolved in water, leading to potential cell swelling.
- Hypertonic Solutions: Higher solvent concentration compared to solute; example includes purified water with minimal solute, causing cells to lose water and shrink.
Solution Comparisons
- Isotonic Example: 2% solute concentration outside equals 2% inside.
- Hypotonic Example: 1% solute concentration outside versus 2% inside means water moves into the cell.
- Hypertonic Example: 2% solute outside compared to 0% inside results in water moving out of the cell.
Additional Concepts
- Types of Solutions: Isotonic, hypotonic, and hypertonic are critical for understanding cell behavior in different environmental conditions.
- Water Movement: Water moves based on solute concentration differences; moves from lower to higher solute concentrations to achieve balance.
- Passive Transport: Movement of substances across cell membranes without energy use; driven by concentration gradients.
