Diffusion, Osmosis and Active Transport
- Diffusion
- Movement of particles from an area of high concentration to an area of low concentration.
- Doesn't require energy
- Molecules
- Osmosis
- Movement of water from an area of high concentration to an
area of low concentration.
- Doesn't require energy
- Water
- Through a partially permeable membrane
- Active Transport
- Movement of particles against the concentration gradient.
- Requires energy (from
respiration)
- Essential molecules
