By diffusion the molecules move from an area of high concentration to an area of low concentration and also by active process.
Explanation:
- Water, carbon dioxide, oxygen, ions etc., cross the cell membrane by a type diffusion 'osmosis'.
- Diffusion is a principle method of movement of substances across the cell membrane.
- By diffusion, the molecules passively move from an area of high concentration to an area of low concentration and also by active process, the molecules move against the concentration gradient.
