Directions for coloring and labeling the diagram:
1.
Label the hydrophillic region of the
phospholipid bilayer and shade it red.
2. Label the hydrophobic region of the
phospholipid bilayer and shade it yellow.
3. Label any protein and color all of the
proteins blue
4. Label a carbohydrate and color all of the
carbohydrates green

1. Looking at the diagram, describe the locations of the hydrophilic and the hydrophobic
regions on the cell membrane.
2. What is the difference between the hydrophilic molecules and hydrophobic molecules?
3. Looking at the diagram, how can you tell if the carbohydrates on the cell membrane are
monosaccharides, disaccharides or polysaccharides? What is the function of the
carbohydrates on the cell membrane?
4. Looking at the diagram, how does the structure of the integral protein allow it to perform its
function?
5. How are the functions of the integral protein and the alpha helix protein similar?
6. Differentiate between peripheral proteins and integral protein?
7. Explain why this structure of the cell membrane is referred to as the fluid mosaic model.
