Chapter 5 Cell Transport
1. .Refer to the illustration above. Which cell (1, 2, 3, 4) is most likely to lose both water molecules and solute
molecules?
2. Refer to the illustration above. In this system, where would the solute molecules in cell 2 are most likely move?
3. .Refer to the illustration above. Which scenario would the direction of water molecules most likely to diffuse?
4. During your lab, when I dropped food coloring in a beaker of water, what example was I showing?
5. Sugar molecules are big and cannot directly enter cells. What process uses carrier proteins to help larger molecules
pass into the cell?
6. Why is the sodium-potassium pump important to your body? Explain the process. (pg 103-104)
7. Give 3 examples of passive transport. (Section 5-1 pgs. 97-100)
8. Give some examples of active transport? (uses ATP) (section 5-2 pgs.103-106)
9. What is endocytosis? What are 2 examples of endocytosis?
10. What is exocytosis?
11. What is ATP? What does it do for your body?

Practicing Writing GOOD Essays (use vocabulary words from Ch 5)
26. Why is it dangerous for humans to drink ocean water? Write your answer in the space below. (Think of this
at a cellular level in your body. Think of solute concentrations and the terms: osmosis, hypertonic, hypotonic,
and isotonic)
27. Distinguish the difference between passive transport and from active transport. Give examples of each. Write
your answer in the space below.
28. Why do supermarkets spray water on their produce? (Think of this process at a cellular level in the plant
produce. Think of solute concentrations and the terms: osmosis, hypertonic, hypotonic, and isotonic.)
