This powerpoint is purposefully made for iGCSE Biology students using the most recent Cambridge syllabus.

It covers the following criteria - 3.1 Diffusion

Core

1. Describe diffusion as the net movement of particles from a region of their higher concentration to a region of their lower concentration (i.e. down a concentration gradient), as a result of their random movement

2. State that the energy for diffusion comes from the kinetic energy of random movement of molecules and ions

3. State that some substances move into and out of cells by diffusion through the cell membrane

4. Describe the importance of diffusion of gases and solutes in living organisms

5. Investigate the factors that influence diffusion, limited to: surface area, temperature, concentration gradient and distance
