Movement of Substances Across the Cell Membrane

This topic covers the processes of diffusion, osmosis, and active transport. Students will experiment with factors affecting these processes and investigate their effects on plant and animal tissues, such as plasmolysis and turgidity. Understanding these mechanisms is crucial for answering ECZ exam questions on cellular physiology and applying biological principles to real-life situations, like water absorption in plants. It reinforces the CBC's focus on practical investigation and conceptual understanding in biology.
