- Diffusion, Osmosis and Active Transport
- Diffusion
- Diffusion is the passive overall movement of particles from a region of their higher concentration to a region of their lower concentration
- Osmosis is a specific case of Diffusion
- Osmosis is the overall movement of water from a dilute to a more concentrated solution through a partially permeable membrane
- A partially permeable membrane is just one allows certain substances to diffuse through it
- Plants take in water by Osmosis. there is usually a higher concentration of water in the soil than there is inside the plant
- Active Transport
- Active transport is the overall movement of chemicals across a cell membrane from a region of lower concentration to a region of higher concentration using energy released by respiration
- Diffusion
