This resource is a recap of the content in the Cell Structure and Transport lesson series prepared to the new AQA biology specification. It suits a year 10 group that has already covered some of this material previously at Year 9 or it could be used as a revision lesson(s) for a Year 11 group. It includes extension materials with extra and harder questions for those pupils that finish early. It has a variety of tasks: a multiple choice quiz; a gap fill exercise; converting units exercise; magnification and image size calculation activity; true or false type exercise (light or electron microscope); surface area to volume ratio calculation activity; choose the correct word to describe how alveoli are adapted for exchanging materials. The activities are fully incorporated into the powerpoint so there is not tonnes of photocopying (apart from one worksheet).
