Plasma Membrane
1. The plasma membrane is known as the __________________ model.
2. The three parts that make up the structure of the plasma membrane are:
a. ________________________
b. ________________________
c. ________________________
3. What structure is considered the ID tag for the cell and where is it located (inside or outside the
cell)? ________________________________________________
4. The lipid heads are (hydrophilic/hydrophobic) while the lipid heads are
(hydrophilic/hydrophobic).
5. The term that describes how the plasma membrane will allow certain things to enter the cell
while keeping other things out of the cell is called _______________________.
6. A protein that spans the entire width of the lipid bilayer is called _________________, while a
protein that is located only on one side of the lipid bilayer is called ________________.
7. Draw a cross section of the lipid bilayer, including the two types of proteins named in #6.
8. Describe the structure of the cell wall.

Cell Transport
9. Cell transport that involves a protein transporting solutes from an area of high concentration to
low concentration is known as ___________________.
10. Osmosis is the diffusion of __________________.
11. Diffusion, osmosis, and facilitated diffusion are all types of ___________________.
12. What are the types of pores that help water move through the plasma membrane?
_________________
13. A cell that is placed in a hypertonic solution will (shrink/swell) because water moves (into/ out
of) the cell.
14. A cell that is placed in a hypotonic solution will (shrink/swell) because water moves (into/out of)
the cell.
15. When the net movement of water between a cell and the solution is 0, what type of solution is
the cell in? ____________________
16. What will happen to the shape of the cell from #15? ___________________________________
17. When molecules move across the cell membrane from an area of low concentration to high
concentration, what type of cell transport occurs? _______________________
18. Describe the difference between facilitated diffusion and transport proteins.
