Diffusion in a leaf |
Materials include: Oxygen, glucose & carbon dioxide. Outside the leaf is a high concentration of CO2 so it diffuses into the leaf. The concentration of O2 is high in the cell so it diffuses out of the cell. Carbon Dioxide + water = glucose + oxygen |

Diffusion in the small intestine |
Inside wall is thin allowing food molecules to pass through into the bloodstream. Food is then carried to where it is needed. Large insoluble substances cannot pass through. |
