Diffusion
- Diffusion in plants
- Carbon dioxide gas diffuses in to the leaf
- Through the Stomata
- Finds its way to the photosynthesising cells
- It is then all used up
- Oxygen produced by photosynthesis
- Concentration is higher in the leaf than the surroundings
- It then diffuses out of the Stomata
- It then diffuses out of the Stomata
- Concentration is higher in the leaf than the surroundings
- Oxygen produced by photosynthesis
- It is then all used up
- Finds its way to the photosynthesising cells
- Through the Stomata
- Carbon dioxide gas diffuses in to the leaf
- Diffusion in the cell membrane
- Carbon dioxide and oxygen can easily pass through the thin layer of cell membrane
- Cell membrane is permeable
- Cell membrane is permeable
- Carbon dioxide and oxygen can easily pass through the thin layer of cell membrane
- Diffusion in animals
- Oxygen diffuses across the thin cell walls of the alveoli of mammals
- Into the blood
- Oxygen travels around the body in the blood stream
- Then diffuses across membranes of respiring cells
- Carbon dioxide diffuses in the opposite direction
- Carbon dioxide diffuses in the opposite direction
- Then diffuses across membranes of respiring cells
- Oxygen travels around the body in the blood stream
- Into the blood
- Lungs have adapted to have many alveoli
- Thus increasing the surface area available for diffusion
- Thus increasing the surface area available for diffusion
- Oxygen diffuses across the thin cell walls of the alveoli of mammals
