Cell Biology 4: Diffusion and Exchange Surfaces

A focused, teacher-led GCSE Science lesson covering diffusion and exchange surfaces, including concentration gradients, factors affecting the rate of diffusion, surface area to volume ratio and adaptations of exchange surfaces. Students will develop their understanding of how substances move into and out of cells, why larger organisms need specialised exchange surfaces and how structures such as the lungs, small intestine, gills and roots are adapted for efficient exchange, with a strong focus on calculations and exam-style questions.

This is a single recorded online lesson for GCSE Science students studying AQA Higher Tier, suitable for both Combined Science and Triple/Separate Biology.
