ANS: T DIF: Synthesis REF: Page 67 TOP: Functional Anatomy of Cells 2. An important function of the cell membrane is the maintenance of cell integrity. ANS: T DIF: Synthesis REF: Page 69 (Table 3-3) TOP: Cell Membrane 3. Peroxisomes contain enzymes that detoxify harmful substances. ANS: T DIF: Memorization REF: Page 76 TOP: Peroxisomes 4. The outer portion of the cell membrane is hydrophobic, or water-loving. ANS: F DIF: Memorization REF: Page 70 TOP: Cell Membrane 5. Ribosomes attached to the endoplasmic reticulum are responsible for making proteins to be exported out of the cell. ANS: T DIF: Memorization REF: Page 73 TOP: Rough ER 6. The functions of the nucleus are regulated by RNA. ANS: F DIF: Memorization REF: Page 78 TOP: Nucleus 7. The major direct cell connections are tight junctions, gap junctions, and desmosomes. ANS: T DIF: Memorization REF: Page 83 TOP: Cell Connections 8. Tight junctions do not allow molecules to spread through the cracks between cells. ANS: T DIF: Memorization REF: Page 83 | Page 84 TOP: Cell Connections 9. Gap junctions are found in the small intestine. They allow molecules to flow between cells. ANS: F DIF: Memorization REF: Page 83 TOP: Cell Connections 10. The number of mitochondria in a cell is basically related to its degree of activity. ANS: T DIF: Memorization REF: Page 77 TOP: Mitochondria 11. The cell’s internal supporting framework is called the cytoskeleton. ANS: T DIF: Memorization REF: Page 79 TOP: Cytoskeleton 12. The size of a cell’s nucleolus is indirectly related to the amount of protein the cell produces. ANS: T DIF: Memorization REF: Page 78 TOP: Nucleus 13. Heart muscle cells are joined by gap junctions to facilitate the movement of electrical impulses. ANS: T DIF: Memorization REF: Page 83 TOP: Cell Connections 14. Cell connections called desmosomes are like Velcro holding cells together. ANS: T DIF: Memorization REF: Page 83 TOP: Cell Connections 15. Cilia are longer and more numerous than flagella. ANS: F DIF: Memorization REF: Page 82 TOP: Cell Extensions 16. Nucleic acid is DNA. ANS: F DIF: Memorization REF: Page 78 TOP: Nucleus 17. The thinnest cell fibers are tiny, hollow tubes called microtubules. ANS: F DIF: Memorization REF: Page 79 | Page 80 TOP: Cell Fibers 18. The plasma membrane can be described as a double layer of phospholipid molecules. ANS: T DIF: Synthesis REF: Page 70 TOP: Cell Membrane 19. Generally, the more active a cell is, the fewer mitochondria it will contain. ANS: F DIF: Application REF: Page 77 TOP: Mitochondria 20. Light microscopy is inferior to electron microscopy. ANS: T DIF: Synthesis REF: Page 80 (Figure 3-15) TOP: Cell Fibers 21. The “typical” cell described in Chapter 3 is very similar to most of the cells in the human body. ANS: F DIF: Memorization REF: Page 68 TOP: The Typical Cell 22. The watery fluid in the cell is called cytosol. ANS: T DIF: Memorization REF: Page 69 (Table 3-3) TOP: Cell Structures 23. Water-soluble substances easily pass through the cell membrane. ANS: F DIF: Memorization REF: Page 71 TOP: Cell Membrane 24. Glycoproteins on the cell membrane would prevent someone with type A blood from accepting type B blood. ANS: T DIF: Application REF: Page 72 TOP: Cell Membrane 25. Rough endoplasmic reticulum looks rough because there are mitochondria attached to it. ANS: F DIF: Memorization REF: Page 73 TOP: Endoplasmic Reticulum 26. Proteins in the cell membrane can control the movement of material through the cell membrane. ANS: T DIF: Memorization REF: Page 72 TOP: Cell Membrane 27. Smooth endoplasmic reticulum is the organelle that supplies membrane material for use throughout the cell. ANS: T DIF: Memorization REF: Page 74 TOP: Endoplasmic Reticulum 28. Ribosomes are only found attached to endoplasmic reticulum. ANS: F DIF: Memorization REF: Page 74 TOP: Ribosomes 29. The main function of the ribosome is to provide energy to the cell. ANS: F DIF: Memorization REF: Page 74 TOP: Ribosomes 30. The Golgi apparatus helps to prepare material for export from the cell. ANS: T DIF: Memorization REF: Page 74 TOP: Golgi Apparatus 31. The protein-processing units of the Golgi apparatus are called cisterna. ANS: T DIF: Memorization REF: Page 74 TOP: Golgi Apparatus 32. In certain situations, cells “commit suicide.” This function would be carried out by the lysosomes. ANS: T DIF: Application REF: Page 76 TOP: Lysosomes 33. The catalase in the peroxisomes reacts to detoxify carbon dioxide. ANS: F DIF: Memorization REF: Page 77 TOP: Peroxisomes 34. The inner folds of the mitochondria are called cisterna. ANS: F DIF: Memorization REF: Page 77 TOP: Mitochondria 35. It is likely that a muscle cell would have more mitochondria than a fat cell. ANS: T DIF: Application REF: Page 77 TOP: Mitochondria 36. One of the main functions of the mitochondria is to supply the cell with ATP. ANS: T DIF: Memorization REF: Page 77 TOP: Mitochondria 37. The name nucleus comes from the Greek word for color. ANS: F DIF: Memorization REF: Page 78 TOP: Nucleus 38. Chromosomes and chromatin are both forms of DNA. ANS: T DIF: Application REF: Page 78 TOP: Nucleus 39.
