Cell membrane sketch On the front: • Make a sketch of the cell membrane including saturated and unsaturated phospholipids, membrane proteins and cholesterol. • Somewhere on the front, a phospholipid needs to be drawn and the parts labeled. Explain which parts are polar and non-polar as well. On the back: • Please explain the functions of the cell membrane in complete sentences. • Explain the FLUID MOSAIC MODEL and how it applies to your sketch. • Explain the functions of membrane proteins and cholesterol in the cell membrane. • Explain how an organism’s cell uses unsaturated and saturated phospholipids in its cells to adapt (if you don’t remember, or don’t understand…ask) to its environment.
