AO2 – application of earlier learning on features that increase the rate of exchange, to explain features that reduce loss in xerophytic plants. Learning objective Time taken Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources Adaptations of gas exchange surfaces, shown by gas exchange in single-celled organisms, insect tracheal systems and fish gills. Structural and functional compromises between gas exchange and the limitation of water loss shown by terrestrial insects. 0.4 weeks Explain the adaptations of single-celled organisms for efficient gas exchange. Describe the structure of insect tracheal systems. Explain how the tracheal system is adapted to allow efficient gas exchange. Explain how tracheal systems balance the needs Learning activities: teacher led explanation about the gas exchange systems within fish and insects and how they are adapted exam questions. Skills developed by learning activities: AT j – dissect the gas exchange system of a bony fish and/or an insect AT d/AT e – use an optical microscope to examine and draw prepared mounts of the Past exam paper material: June 2013 – June 2009 – Q8a BIOL2 Jan 2012 – BIOL2 Jan 2010 – Q8 Rich question: Explain the adaptations present in fish gills and insect tracheal systems.
