- Diffusion
- occurs when gas particles spread out
- gases move from a high concentration area to a low concentrated area
- concentration gradient
- Examples
- amino acids, sugars etc moving from gut to the blood capillaries by moving into the blood stream
- oxygen moving from lungs to blood cells
- roots have pure water and the ground has the nutrients which will be absorbed.
