In this video, we start looking at the structure of cell membranes. First we explore the structure of phospholipids and the phospholipid bilayer. We then explore the role of cholesterol in membranes. Finally, we look at what is meant by the fluidmosaic model of membrane structure.

This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
