Egg Osmosis Post-Lab
Date:____________
Osmosis is the movement of water across the plasma membrane in which the solute moves from an
area of high concentration to an area of low concentration.
For each solution below, use the diagram of the naked eggs in solution to identify the movement of
water. Use the results (data) of the egg osmosis lab to help guide you.
Water Solution:
1. Draw arrows to show the water movement in or out of the egg.
2. Did the cell shrink, swell, or stay the same?
3. There is a greater concentration
of H2O where? (Circle one)
A. Inside the egg
B. Outside the egg
C. The concentration is the same
4. This shows the cell in a: Hyper/Hypo/Isotonic solution.
Vinegar Solution:
1. Draw arrows to show the water movement in or out of the egg.
2. Did the cell shrink, swell, or stay the same?
3. There is a greater concentration
of H2O where? (Circle one)
A. Inside the egg
B. Outside the egg
C. The concentration is the same
4. This shows the cell in a: Hyper/Hypo/Isotonic solution.
Corn Syrup Solution:
1. Draw arrows to show the water movement in or out of the egg.
2. Did the cell shrink, swell, or stay the same?
3. There is a greater concentration
of H2O where? (Circle one)
A. Inside the egg
B. Outside the egg
C. The concentration is the same
4. This shows the cell in a: Hyper/Hypo/Isotonic solution.

5. How are eggs and cells similar?
6. The movement of water across a semi permeable membrane is?
7. How are solutions classified?
8. A solution with a high amount of dissolved solute is?
9. What makes a solution hypertonic?
10. You soak your hands in dishwater, you may notice that your skin absorbs water and
swells into wrinkles. This is because your skin cells are ________________ to the _________________
dishwater.
11. Two solutions that have the same solute concentration are called?
