CIE IGCSE Biology Topic 3 REVISION (Movement in and out of cells)

This revision resource includes exam questions, understanding checks and quiz competitions, all of which have been designed with the aim of motivating and engaging the students whilst they assess their understanding of the content found in topic 3 (Movement in and out of cells) of the CIE IGCSE Biology specification for examination in June and November 2020 and 2021. This revision resource contains a detailed and engaging PowerPoint (42 slides) and associated worksheets, some of which have been differentiated to help and challenge differing abilities.

The range of activities have been designed to cover as much of the Core and supplement content as possible but the following sub-topics have been given particular attention:

• Active transport as the movement of particles against their concentration gradient using energy from respiration
• The importance of active transport as demonstrated by the absorption of mineral ions by the root hair cells
• The movement of water across cell membranes by osmosis
• The importance of osmosis and water potential in the uptake of water by plants
• The effects on plant cells of immersion into solutions of different concentrations
• The importance of turgor pressure for a plant
• Diffusion as the net movement of particles with the concentration gradient
• Recognising the factors that influence the rate of diffusion

In addition, topics from other modules such as specialised plant cells are covered so that students can see the importance of being able to make connections and links between Biological topics.
