Name ________________________- Cell Membrane Diagram (lipid bilayer,fluid mosaic model) Label and color the parts as described below. Polar heads- yellow Phospholipid tails- green Transport proteins- red Cholesterol- blue Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails. Review The cell membrane is sometimes referred to as the _____________________. The cell membrane is made up of two layers of ________________________, with many ______________ imbedded throughout to help transport molecules in/out of the cell. Each phospholipids has a ____________ head facing out, and 2 non-polar ________ facing in. Name ________________________-
