Cell Membrane Structure and Function

Type of Resource



This activity includes two hands-on experiments and numerous analysis and discussion questions to help students understand how the molecular composition and organization of a cell membrane result in its selective permeability. In the hands-on experiments, students test whether a synthetic membrane is selectively permeable and students observe how a layer of oil can be a barrier to diffusion of an aqueous solution. Then, students learn how the phospholipid bilayer and membrane proteins play key r
