Cell Cycle Images and Questions

  1. 1. Cell Cycle <br />Additions to accompany notes<br />
  2. 2. Surface Area to Volume Ratio<br />Surface Area<br />Volume<br />As a cell increases in size, what increases the fastest?<br />
  3. 3. If an imaginary cube-shaped cell has a length of 6 cm, its ratio of surface area to volume is<br />1 : 1. <br />6 : 1. <br />36 : 1. <br />1 : 6.<br />
  4. 4. When a growing cell undergoes cell division, each new cell gets <br />half the DNA from the original cell. <br />twice as much DNA as the original cell. <br />a random sample of the DNA in the original cell. <br />a full copy of all the DNA in the original cell. <br />
  5. 5. The process by which a cell divides into two new daughter cells is called<br />cell growth. <br />cell division. <br />DNA replication. <br />mitosis.<br />
  6. 6. When one cell divides in two, what happens to the surface area to volume ratios in the new cells?<br />There is no change in the amount of material exchanged. <br />Each new cell can exchange more material than the original cell. <br />Each new cell can exchange less material than the original cell. <br />The two new cells cannot be compared to the original cell.<br />

  9. 9. Copyright Pearson Prentice Hall<br />Section 10-2<br />Prophase<br />Spindle forming<br />Prophase<br />Chromosomes (paired chromatids)<br />Centromere<br />Click to Continue<br />Mitosis<br />
  10. 10. Copyright Pearson Prentice Hall<br />Mitosis<br />Spindle <br />forming<br />Prophase<br />Prophase is the first and longest phase of mitosis.<br />The centrioles separate and take up positions on opposite sides of the nucleus.<br />Centromere<br />Chromosomes<br />(paired chromatids)<br />
  11. 11. Copyright Pearson Prentice Hall<br />Mitosis<br />Spindle <br />forming<br />The centrioles lie in a region called the centrosome.<br />The centrosomehelps to organize the spindle, a fanlike microtubule structure that helps separate the chromosomes.<br />Centromere<br />Chromosomes<br />(paired chromatids)<br />
  12. 12. Copyright Pearson Prentice Hall<br />Mitosis<br />Spindle <br />forming<br />Chromatin condenses into chromosomes.<br />The centrioles separate and a spindle begins to form.<br />The nuclear envelope breaks down.<br />Centromere<br />Chromosomes<br />(paired chromatids)<br />

  14. 14. Copyright Pearson Prentice Hall<br />Mitosis<br />Centriole<br />Metaphase<br />The second phase of mitosis is metaphase.<br />The chromosomes line up across the center of the cell.<br />Microtubules connect the centromere of each chromosome to the poles of the spindle.<br />Spindle<br />
  15. 15. Copyright Pearson Prentice Hall<br />Individual chromosomes<br />Anaphase<br />Mitosis<br />Anaphase<br />
  16. 16. Copyright Pearson Prentice Hall<br />Mitosis<br />Anaphase<br />Anaphase is the third phase of mitosis.<br />The sister chromatids separate into individual chromosomes. <br />The chromosomes continue to move until they have separated into two groups.<br />Individual<br />chromosomes<br />
  17. 17. Copyright Pearson Prentice Hall<br />Nuclear envelope reforming<br />Telophase<br />Mitosis<br />Telophase<br />
  18. 18. Copyright Pearson Prentice Hall<br />Mitosis<br />Telophase<br />Telophase is the fourth and final phase of mitosis.<br />Chromosomes gather at opposite ends of the cell and lose their distinct shape.<br />
  19. 19. Copyright Pearson Prentice Hall<br />Mitosis<br />A new nuclear envelope forms around each cluster of chromosomes.<br />
  20. 20. Copyright Pearson Prentice Hall<br />Cytokinesis<br />Cytokinesis<br />Cytokinesis<br />
  21. 21. Copyright Pearson Prentice Hall<br />Cytokinesis<br />During cytokinesis, the cytoplasm pinches in half.<br />Each daughter cell has an identical set of duplicate chromosomes<br />
  22. 22. Copyright Pearson Prentice Hall<br />Cytokinesis in Plants<br />In plants, a structure known as the cell plate forms midway between the divided nuclei.<br />Cell plate<br />Cell wall<br />
  23. 23. Copyright Pearson Prentice Hall<br />10-2<br />The series of events that cells go through as they grow and divide is called <br />the cell cycle. <br />mitosis. <br />interphase. <br />cytokinesis. <br />
  24. 24. Copyright Pearson Prentice Hall<br />10-2<br />The phase of mitosis during which the chromosomes line up across the center of the cell is <br />prophase. <br />metaphase. <br />anaphase. <br />telophase.<br />
  25. 25. Copyright Pearson Prentice Hall<br />10-2<br />Cytokinesis usually occurs <br />at the same time as telophase. <br />after telophase. <br />during interphase. <br />during anaphase <br />
  26. 26. Copyright Pearson Prentice Hall<br />10-2<br />DNA replication takes place during the<br />S phase of the cell cycle. <br />G1 phase of the cell cycle. <br />G2 phase of the cell cycle. <br />M phase of the cell cycle. <br />
  27. 27. Copyright Pearson Prentice Hall<br />10-2<br />During mitosis, “sister” chromatids separate from one another during<br />telophase. <br />interphase. <br />anaphase. <br />metaphase. <br />
