Cell Biology 5: Osmosis and Active Transport

A focused, teacher-led GCSE Science lesson covering osmosis and active transport, including water movement across partially permeable membranes, concentration gradients, movement of substances against a concentration gradient and the role of energy in active transport. Students will develop their understanding of how substances move into and out of cells, apply this knowledge to examples such as mineral ion uptake in plant roots and absorption in the small intestine, and compare diffusion, osmosis and active transport, with a strong focus on exam-style questions.
