Goal: The study of biology is really the study of living cells. In order to understand all living things we need
to understand the cell its parts and their functions. You should also be aware plant and animal cells
have both similarities and differences.
1. Label and state the function of each organelle listed; golgi body, smooth ER, rough ER,
mitochondria, nuclear membrane, nucleus, nucleolus, vacuole, centriole. (18 marks)
2. Cyanide binds to at least one of the molecules involved in the production of ATP. Cyanide maybe
a component of some pesticides and can be breathed in or absorbed through the skin. Where would
you expect to find a concentration of cyanide?
a. mitochondria
b. ribosmes
c. lysosomes
d. ER
3. Why would cells found lining the stomach have large numbers of golgi bodies and ribosomes? (2
marks)
4. Hormones are the body’s chemical messengers. Protein hormones, such as insulin, must attach
to a receptor site on the cell membrane while steroid hormones, such as sex hormones, can
diffuse directly through the phospholipid bilayer. Explain why steroid hormones can pass directly
into the cytoplasm of the cell. (2 marks)
5. Cells of the pancreas will incorporate radioactively labeled amino acids into a protein. This
“tagging” of newly synthesized proteins allow researchers to track the location of these proteins in
a cell. In this case, we are tracking an enzyme that is eventually secreted by pancreatic cells.
Which of the following is the most likely pathway for movement of this protein in the cell?
a. ER, golgi body, nucleus
b. golgi body, ER, nucleus
c. nucleus, golgi body ER
d. ER, golgi body, vesicle fusing with plasma membrane
e. ER, lysosome, vesicle fusing with the plasma membrane
6. How do lysosomes and vacuoles work together? (1 mark)
