Biology Unit 01: Cell Structure and Funtion Review

1. 1. Describe the structure and function of the cell organelles: mitochondria, nucleus, cell membrane, vacuole, ribosome, endoplamic reticulum, golgi, chloroplast, cell wall.
2. 2. What are the major differences between prokaryotic and eukaryotic cells?
3. 3. What are two organelles that a plant cell has that an animal cell lacks?  What is an organelle that a plant has a much larger version of than an animal cell?
4. 4. Know the structural hierarchy from atoms to organisms.
5. 5. Watch this video on the endosymbiotic theory. Take notes on it and be prepared to answer questions about it on the test. What evidence supports the theory? 
6. 6. What are the basic structures of a virus.  Why are not viruses considered to be living things?  Compare and contrast the structures found in viruses, to the structures found in cells. 
7. 7. The nuceus of eukaryotes contains DNA.  What does the "NA" in DNA stand for?  What does it do?  Is it in prokaryotes? If so, what are the differences between DNA in prokaryotes and eukaryotes?
8. 8. Recognize the difference in drawings of: plant and animal cells, bacteria, and viruses.
9. 9. Have a general idea of the differences in the sizes of plant and animal cells, bacteria, and viruses.  In the video, they are all viruses until you get staphylococcus, which is a bacteria.  The bacteria end at the red blood cell.
10. 10. Know the key structures found in viruses.
11. 11. Here is a picture of bacteriaphage viruses attacking a bacterium. Notice the difference in size between viruses and bacteria.
12. 12. Here is a picture of plant cells (left) and bacteria cells (right). Both pictures were taken at the same magnification. Notice the difference between the sizes. Also, notice how the plant cells are all part of the same tissue and the bacteria are unicellular.    
13. 13. The night before the Marathon to Marathon, the there is a spaghetti dinner for the runners. What type of biomolecule is in spaghetti that makes it useful for a run?
