Here is the short assignment about the Cell Membrane that students started on Wednesday.

Pages 204 -205 and Figure 7-13 on the bottom of 204

1.Draw a simplified version of the diagram. 
2.Identify and describe the functions of each of the components that make up a cell membrane:
§Lipids (hydrophilic head and hydrophobic tail)
§Lipid Bilayer
§Membrane Proteins
§Carbohydrate Chains
3.Why is The Fluid Mosaic Model a good description of the cell membrane?
4.Some substances can cross the cell membrane…others cannot.  Why?
5.The membrane is said to be Selectively Permeable.  What does this mean?
