- Diffusion
- spreading out of particles from an area of high concentration to an area of low concentration
- concentration gradient
- happens in solutions and gases
- bigger difference in concentration- faster diffusion rate
- very small molecules can diffuse through the cell membrane
- small molecules- oxygen, glucose, amino acids and water
- big molecules can't fit- starch and proteins
- net movement
