Complete the following prior to coming to lab, use your textbook for reference. Type the
answers, print them out, and turn them in at the BEGINNING of lab.
Part I: Define the following.
1. Diffusion
2. Concentration gradient
3. Equilibrium
4. Osmosis
5. Hypotonic
6. Hypertonic
7. Isotonic
8. Tonicity
9. Crenate
10. Lyse
11. Active process
12. Passive process
13. Carrier mediated
14. Solute
15. Solvent
Part II.
1. Diffusion is a
concentration to a
process where a solute moves from a
concentration.
2. Osmosis is the movement of
concentration to a solution with a
from a solution with a
concentration.
3. Isotonic saline and 5% dextrose in water are solutions considered isotonic to human blood.
What effect on red blood cells would you expect if a patient were given these fluids
intravenously? A solution of 10% dextrose in water is hypertonic to human blood. What
would happen if you were to infuse your patient with this solution?
4. Gatorade and other sports drinks are actually hypotonic solutions. How do these drinks
rehydrate their user’s cells?
