The adaptations of cells for rapid transport across internal and external membranes. 0.2 Explain the adaptations of specialised cells maximising the rate of transport across their internal and external membranes (could be linked to Fick’s law). Explain how surface area, number of channel or carrier proteins and differences in gradients of concentration or water potential affect the rate of movement across cell membrane. Learning activities: questioning to assess understanding of adaptations to increase rate of diffusion calculate surface area: volume ratio of cells with folds, when supplied with appropriate data. (Could address with section 3.3.1) exam questions. Skills developed by learning activities: AT d – use optical microscopes to observe cells that are adapted for rapid exchange eg root hair cells, epithelial cells of the small intestine MS 0.3/MS 4.1 – calculate surface area: volume ratios of extended exam answers. Past exam paper material: BIOL1 June 2011 Q8b Rich questions: what does Fick’s law state? what common adaptations do cells of exchange surfaces have? Extension Microscopy of cells that have adaptations for exchange. Ask pupils to identify and explain these adaptations.
