Copyright © 2015 Henry Exham • Can you write a definition for diffusion, osmosis and active transport? • Can you explain how surface area to volume ratio, temperature, and concentration gradient affect the rate at which these processes work? • Can you describe a simple experiment to demonstrate diffusion using a non-living system? 1.1 Life Processes – Movement in and out of cells Objectives 2

  22. 22. Copyright © 2015 Henry Exham 1.1 Life Processes – Movement in and out of cells Factors affecting the rate of diffusion 22 • As the rate of diffusion relies on the surface area. • The parts of organisms that rely on diffusion therefore tend to have a large surface area.
