Study Guide: Chapter 2 s3

Name: ______Block: ____ Date: ____Mrs. Stone Study Guide: Chapter 10 Prentice Hall Biology Directions: On a separate piece of paper, answer the following questions in complete sentences. Section 10-1 1. How do living things grow? Describe the difference between the cells of an adult animal and a young animal. 2. What are the two main reasons cells divide rather than continue to grow indefinitely? 3. As a cell increases in size, which increases more rapidly, its surface area or its volume? 4. Describe how cell division solves the problems of cell growth.

Section 10-2 5. What must a cell do before it divides? 6. Define mitosis and cytokinesis. 7. What is a chromosome, what is a chromosome made of? 8. How many chromosomes do human cells have? 9. Draw a picture of a replicated chromosome. Label chromatids. 10. Why is it important that sister chromatids are identical? 11. Define centromere. 12. What is the cell cycle? 13. What four phases does the cell cycle consist of? 14. What is interphase? 15. List and describe what occurs during each stage of interphase. 16. What are the four stages of mitosis? 17. Define centrioles and spindle. 18. Draw a diagram of mitosis similar to Figure 10-5, next to each stage write what is happening in the cell. Begin your drawing with prophase and end with cytokinesis. Make sure you have the appropriate number of chromosomes in every stage! 19. How do prokaryotic cells divide? What is the name of prokaryotic cell division? (In your notes) 20. How is cytokinesis in plant cells similar to cytokinesis in animal cells? How is it different? 21. If a cell with 4 chromosomes divides how many chromosomes will each daughter cell have?

Section 10-3 22. What are some cells in the human body that divide relatively quickly, what are some cells that divide more slowly? 23. Describe what is happening in figure 10-7. 24. How does figure 10-7 relate to what happens to cells in the body. 25. What does the protein cyclin do? 26. What are internal regulators? 27. What are external regulators? 28. Define cancer. 29. What are some causes for the loss of growth control that characterizes cancer? 30. What is p53? 31. Imagine that you are developing a drug that will inhibit the growth of cancer cells. Use your knowledge of the cell cycle to describe how the drug would target and prevent the multiplication of cancer cells.
