Study Notes
Diffusion in Photosynthesis
- A simple example of diffusion is the movement of carbon dioxide into a photosynthesizing leaf cell.
Carbon Dioxide Concentration
- The carbon dioxide concentration is likely to be lower in a photosynthesizing leaf cell compared to its environment when photosynthesis is occurring.
Role of the Cell Membrane
- The cell membrane plays a role in regulating the movement of substances, including carbon dioxide, into and out of the cell.
Carbon Dioxide Usage
- In photosynthesis, carbon dioxide is used faster than it is produced.
