Fall Semester Review Part 2Biology Pre AP

1. What are the levels of organization from atom to biosphere?

Cell Membrane2. Below is a diagram of a cell membrane. Circle the three biomolecules that make up the cell membrane.

Which biomolecule makes up most of the membrane? __________________________

Below is an image of a lipid molecule.

The image of the single lipid shows something interesting: one end of the lipid loves water and the tail end does not want to be near water! Now look at the image of the cell membrane again. What do you notice about where the ends of the lipid are located? Explain what you see.

Where would water be found by the membrane? Why?
