  1. Chapter 10 Review

  2. You must answer in complete sentences! • Explain TWO problems that can occur when a cell gets too big.

  3. You must answer in complete sentences! • Explain TWO problems that can occur when a cell gets too big. • DNA overload • Exchange of materials

  4. You must answer in complete sentences! 2. What are the two main events of the cell cycle

  5. You must answer in complete sentences! 2. What are the two main events of the cell cycle Interphase and Cell Division (M Phase)

  6. You must show all calculations and units! 3. What is the surface of a cube with a length of 4 cm, a width of 4 cm and a height of 4 cm?

  7. You must show all calculations and units! 3. What is the surface of a cube with a length of 4 cm, a width of 4 cm and a height of 4 cm? • 4x4x6 = 96 cm2

  8. You must answer in a complete sentence! 4. Look at the pictures below (chromatin has been stained red). What phase of mitosis is being shown in each picture? Explain how you know. C A B D

  9. You must answer in a complete sentence! 4. Look at the pictures below (chromatin has been stained red). What phase of mitosis is being shown in picture B? Explain how you know. C A B D A = anaphase (pulled apart); B = Metaphase (chromosomes lined up in middle); C = prophase; D = telophase (two nuclei)

  10. You must show all calculations and units! 5. What is the surface area to volume ratio of a cube with 5 cm sides?

  11. You must show all calculations and units! 5. What is the surface area to volume ratio of a cube with 5 cm sides? SA = 5x5x6 = 150 cm2 V = 5x5x5 = 125 cm3 SA:V = 6:5

  12. Draw a pretty picture! 6. Draw a picture of a duplicated chromosome and label the centromere and sister chromatids.

  13. Draw a pretty picture! 6. Draw a picture of a duplicated chromosome and label the centromere and sister chromatids.

  14. NO need to write in complete sentences! 7. List the phases of mitosis in order !

  15. NO need to write in complete sentences! 7. List the phases of mitosis in order ! Prophase, Metaphase, Anaphase, Telophase (Cytokinesis)

  16. You must answer in a complete sentence! 8. Describe what happens in anaphase.

  17. You must answer in a complete sentence! 8. Describe what happens in anaphase. • Sister chromatids are pulled apart to opposite ends of the cell

  18. You must answer in complete sentences! 9. How do the internal and external regulators help the timing of the cycle?

  19. You must answer in complete sentences! 9. How do the internal and external regulators help the timing of the cycle? Internal – checkpoint inside the cell to regulate when the cell is ready to advance to the next step of the cell cycle External – speed up or slow down the cell cycle

  20. You must answer in complete sentences! 10. How are cancer cells different than other cells?

  21. You must answer in complete sentences! 10. How are cancer cells different than other cells? • Cancer cells can not regulate the cell cycle and divide uncontrollably.

  22. SHOW YOUR WORK! Don’t forget units! 11. Calculate the percent absorption of the cube below.

  23. SHOW YOUR WORK! Don’t forget units! 11. Calculate the percent absorption of the cube below. Total volume = 2x2x2 = 8 cm3 Uncolored volume = 1x1x1 = 1 cm3; colored = 7 cm3 Percent absorption = 7/8 = 87.5%

  24. 12. Draw the circular cell cycle figure (with phase names) from memory. Then check your figure against the one on page 245 in your textbook.
