This resource contains six PowerPoints with numerous animations and videos along with student question sheets to accompany each PowerPoint. The videos are embedded in the PowerPoint and also available as separate mp3 files. These help students to explain:

• the roles of membranes within cells and at the surface of cells
• the fluid mosaic model of membrane structure and the roles of its components
• factors affecting membrane structure and permeability.
• practical investigations into factors affecting membrane structure and permeability
• the movement of molecules across membranes
• the movement of water across membranes by osmosis and the effects that solutions of different water potential can have on plant and animal cells.
• practical investigations into the effects of solutions of different water potential on plant and animal cells.

Everything you’ll need to teach a series of lessons (approximately 5 x 1 hour lessons) on biological membranes; plus two practical lessons which takes approximately 2 hours each.

Each PowerPoint contains the answers to the student question sheets.

There is also an end of topic test with mark scheme and a biological membranes crossword to help embed key words.
