Topic 2.3: Transport across cell membranes (AQA A-level Biology)

This lesson bundle contains 4 fully-resourced lessons that use a wide variety of tasks to engage and motivate the students whilst covering the following specification points in topic 2.3 of the AQA A-level Biology specification:

• The basic structure of cell membranes
• The arrangement of phospholipids, proteins, glycoproteins and glycolipids in the fluid-mosaic model of membrane structure
• The role of cholesterol in membranes
• Simple diffusion and the limitations imposed by the phospholipid bilayer
• Facilitated diffusion and the role of channel and carrier proteins
• Osmosis in terms of water potential
• Active transport
• Co-transport as illustrated by the absorption in the ileum

Hours of planning has gone into the lesson design to ensure that links are made to topics 2.1 & 2.2 as well as to topic 1 (biological molecules) and to differentiate resources where possible to challenge and support all abilities of students
