Study Guide for Test on Cell Organelles, Passive, and Active Transport
(TEST ON NOVEMBER 24th)
1. Compare and Contrast Passive Transport and Active Transport.
(How are they similar? How are they different?) Venn Diagram maybe helpful!
2. Explain endocytosis and exocytosis.
3. A cell with a concntration of 5% sugar is place into a beaker with a concentration of 20% sugar. What will happen to the cell in this type of environment?
4. Explain how a cell tries to reach equilibrium. What is the name of the solution when a cell is said to reach equilibrium?
5. What is the function of the following organelles?
| Organelle | Function |
| Nucleus | |
| Ribosomes | |
| Chloroplast | |
| Cell Membrane | |
| Cell Wall | |
| Mitochondria | |
| Endoplasmic Reticulum | |
| Golgi Apparatus |
6. Label the cell organelles on the cell diagram.
7. What is diffusion?
8. What is osmosis?
9. Explain how an ion channel works. Is it active or passive transport.
10. H ow does a sodium-potassium pump move sodium and potassium ions? Why does this require energy?
11. If a cell is place in a solution and the cell shrinks, what type of solution was the cell placed? (Hint: hypertonic, hypotonic, or isotonic).
12. How are receptor and carrier proteins different?
13. Explain how a protein is made and then transported throughout the cell. Name the organelles and the role they play in protein synthesis.
14. Name at least two types of passive transport and explain each.
15. Name at least two types of active transport and explain each.
16. Tell the different functions of the cell membrane and how it performs those functions.
17. Draw a diagram of endocytosis and exocytosis.
Don’t forget to be reviewing information from first quarter. This information will be included on the semester final in January 2010.
