Name:________________________Per:____Date:______ Chapter 10 Quiz Review Mitosis Question 1. As a cell grows – which grows fast – volume or surface area? 2. What are three reasons that cells divide? 3. How fast can E.Coli cells divide? 4. What two types of cells divide on a daily basis? 5. How do cells know when to stop growing? 6. When cells have uncontrolled growth – what is this called? 7. What are the three (3) stages of cell division? 8. What is the difference between mitosis and cytokinesis? 9. What does “colored body” mean? 10. A chromosome is how many times smaller than the DNA inside? 11. What is chromatin? 12. When DNA is coiled around histones so that it looks like “a ball with string” – what is this structure called? 13. What are the special proteins that DNA coils around called? 14. How are sister chromatids joined? 15. How many chromosomes does the human body cell contain? 16. When we say that the human body cell is diploid – what does this mean? 17. What are the 3 stages of interphase? 18. During which phase of interphase is there cell growth and protein production? 19. During which phase of interphase does the DNA replicate? 20. During which phase of interphase do the organelles replicate? 21. What form is the DNA in during interphase? Answer 22. What are the 4 phases of mitosis – in order? 23. What phase of mitosis is the longest? 24. What is the first phase of mitosis where chromosomes are visible? 25. During which phase of mitosis do centrioles start to move to the poles and spindle fibers appear? 26. During which phase of mitosis do chromosomes attach to the spindle fibers and line up in the middle? 27. During which phase of mitosis do the centromeres split and pull sister chromatids apart? 28. During which phase of mitosis do chromosomes uncoil and go back into chromatin? 29. During which phase of mitosis does a nuclear envelop form around each new nuclei? 30. What is present at the end of mitosis? 31. What process moves inward and pinches in the middle to form two cells? 32. What forms before the cell wall at the end of the cell cycle in plants? 33. What two factors limit the size of a cell? 34. Embryonic stage that consists of a hollow ball of cells 35. Cell specialization 36. Term used to describe a cell that can form any kind of cell and tissue in the body 37. Unspecialized cells that can develop into differentiated cells 38. Cancerous tumor 39. Programmed cell death 40. Proteins that regulate the timing of the cell cycle
