Study Notes
Selective Permeability
- A membrane that allows certain substances to pass through while blocking others is called selectively permeable.
Diffusion
- Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
Osmosis
- Osmosis is a special type of diffusion involving the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration.
Hypertonic Solution
- A solution with a higher concentration of solute compared to the cell is referred to as a hypertonic solution.
