9. $400 What are growth, repair, replacement? Name 2 solid reasons why cells have to divide.

10. $600 What is a cells growing to its max size triggers cell division? This triggers a cell to divide.

11. $800 What is it must duplicate its DNA? What must a cell do before it can divide?

12. $1000 What are Mitosis & Cytokinesis? Cell division occurs in these 2 stages.

13. $200 What is interphase? This must always begin the cell cycle.

14. $400 What are G1, S, and G2? These are the 3 parts of interphase in the correct order.

15. $600 What are Prophase, Metaphase, Anaphase, & Telophase and they make up Mitosis? These phases follow interphase in this specific order and make up what we call this.

16. $800 What is the nucleus? Mitosis is the division of this.

17. $1000 What is the division of the cytoplasm and is not considered a part of mitosis? Cytokinesis is the division of this and is not considered a part of this.

18. $200 What is the centromere? This is the name for the area where 2 chromosomes connect.

19. $400 What is DNA? Chromosomes are made up of this.

20. $600 What are chromatids? Each chromosome is composed of 2 identical “sister” _______.

21. $800 What is prophase? In this phase chromosomes are first seen in the condensed form.

22. $1000 Using the whiteboard, please correctly draw and label a chromosome.

23. $200 What is the nucleus? Mitosis is the division of this.

24. $400 What are Prophase, Metaphase, Anaphase, and Telophase? These are the 4 phases of Mitosis in the correct order.

25. $600 What is to organize fan- like spindles that separate the chromosomes? This is the job of the centrioles during mitosis.

26. $800 What is Metaphase? In this phase the chromosomes line up across the middle before being pulled apart.

27. $1000 What are interphase & cytokinesis? These two things take place within the cell cycle but are not considered part of mitosis.

28. $200 What is sexual reproduction because it promotes diversity in genes? Meiosis is essential for this type of reproduction because it promotes this.

29. $400 What are egg and sperm? The female and male gametes are called this.

30. $600 What is a zygote? This is the name for a fertilized egg.

31. $800 What are 4 new and completely different sperm or eggs? The process of meiosis creates this many new sperm or eggs.

32. $1000 What are 80 chromosomes? If an organism’s gametes contain 40 chromosomes then its young will have this many total chromosomes.

33. $200 What is cancer? Another name for uncontrolled cell growth.

34. $400 What is cyclin? This regulates the timing of the cell cycle in eukaryotic organisms.

35. $600 What is haploid? Term meaning to contain 1 set of chromosomes.

36. $800 What are homologous chromosomes? Name for corresponding chromosomes each from the opposite sex parent.

37. $1000 Mitosis=asexual repro, 1 cell producing 2 identical cells, no exchange of genetic material Meiosis=sexual repro, 2 cells producing 4 diff cells These are 3 distinct differences between Mitosis & Meiosis.
