SBI 3U UNIT 1 – CELLULAR FUNCTIONS

Unit Test is Monday, October 28, 2002 and you should be able to:

1. State and describe the molecules critical to life. (1.1)

2. Identify and describe the structure and function of important biochemical compounds including carbohydrates, proteins, lipids and nucleic acids. (1.1)

3. State the tests and positive results used to identify the nutrients studied in class.(Lab 1A)

4. Identify the structure and function of phospholipids. (1.2)

5. Describe and draw a diagram of the fluid mosaic model of the cell membrane. (1.2)

6. Explain the various transport methods including diffusion, osmosis, facilitated diffusion and active transport. (1.3)

7. Explain the movement of water with reference to cells in isotonic, hypotonic, and hypertonic environments and how cells respond to such environment, i.e. lysis and plasmolysis. (1.3)

8. Explain the processes of endocytosis (phagocytosis and pinocytosis), receptor-mediated and exocytosis. (1.4)

9. Identify the basic features of eukaryotic and prokaryotic cells. (2.1)

10. Describe the structure and function of organelles and other cell structures. (2.1)

17. Explain the flow of energy between photosynthesis and respiration. (3.4)

18. Explain how scientific knowledge of cellular processes is used in technological applications (producing ethanol, as a fuel, clean up of oil spills, use of microbes in the pulp and paper industry) (3.3 and 3.4)
