Practical investigation of whether size affects the rate of diffusion using agar cubes. 3.3.2 Gas exchange knowledge: GCSE Additional Science Exercise increases the rate and depth of breathing. Learning objective Time taken Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources Adaptations of gas exchange surfaces in leaves of dicotyledonous plants (mesophyll and stomata). Structural and functional compromises between gas exchange and the limitation of water loss 0.4 weeks Describe the internal structure of a leaf. Explain how the structure is an adaptation allowing efficient gas exchange.
