1. How Cells Divide Chapter 9-10

2. Cell Division *growth and repair *reproduction

3. Cell Division *divide contents of cell *replicate genetic information 2 parts:

4. Cell Division parent cell daughter cells

5. Prokaryotic cells Binary Fission

6. 1. Replicate the genetic material 2. Divide the cell

7. Cell Division Eukaryotic Cells

8. Chromosomes

9. Cell Division 1. Replicate the genetic material 2. Divide the cell

10. Mitosis *growth and repair Eukaryotic Cells

11. Meiosis *production of gametes Eukaryotic Cells

12. Cell Cycle

13. Interphase Division (meiosis or mitosis)

14. Mitosis Inter- phase

15. Human chromosomes

16. 23 pairs of chromosomes 46 chromosomes haploid number diploid number

17. Human chromosomes 23 pairs 46 chromosomes Homologous pair

18. Homologous chromosomes One from the egg One from the sperm

19. Homologous chromosomes

21. Replicated chromosomes

24. Interphase

25. Prophase

26. Metaphase

27. Anaphase

28. Telophase

29. Cytokinesis

32. Cytokinesis in an animal cell

33. Cancer Cells

35. Meiosis and Sexual Cycles

36. Asexual reproduction

37. Sexual Reproduction

39. Meiosis aka: reduction division 2n n

40. Meiosis aka: reduction division 2n n Gamete formation

41. Meiosis *replicate chromosomes *two cell division phases

42. Meiosis ONE (1) 2n cell FOUR (4) n cells

43. Meiosis I

45. Meiosis I telophase I

46. Meiosis I

47. Prophase I *Crossing over (= synapsis)

49. Meiosis I Prophase I *Crossing over (= synapsis)

50. Meiosis II

53. Meiosis II

54. Meiosis Start: diploid (2n) End: haploid (1n)

55. Meiosis
