  2. Category 1 questions follow

  3. Mitosis involves PMAT I and II Producing gametes Producing haploid cells Producing identical cells to parent cells 10 Category 1

  4. Mitosis involves Only Producing identical cells to parent cells 10 Category 1

  5. How is Mitosis chromosome number different than Meiosis? 20 Category 1

  6. How is Mitosis chromosome number different than Meiosis? Mitosis is haploid- 1n Meiosis is diploid – 2n 20 Category 1

  7. What does not occur in prophase? The nuclear envelope breaks up Tetrads line up at the equator 30 Category 1

  8. What does not occur in prophase? Tetrads are in Meiosis I and they line up at the equator during metaphase 30 Category 1

  9. In what phase are 4 diploid cells produced? a. Mitosis b. Meiosis I c. Meiosis II d. None of these e. a, b and c are correct 40 Category 1

  10. In what phase are 4 diploid cells produced? None of these 40 Category 1

  11. An example of Asexual reproduction includes Regeneration Spores Budding A, b, and c are correct 50 Category 1

  12. Regeneration, spores and Budding are examples of Asexual reproduction 50 Category 1

  13. Category 2 questions follow

  14. What is the big difference between prophase I and II? 10 Category 2

  15. What is the big difference between ? prophase I has 1 cell and prophase II has 2 cells 10 Category 2

  16. When an egg and sperm unite a ____________is produced. gamete A sex cell Zygote Haploid cell 20

  17. When an egg and sperm unite a ____________is produced. Diploid zygote 20 Category 2

  18. The combining of an egg and sperm is called Fertilization Pollination 30 Category 2

  19. The combining of an egg and sperm is called Fertilization 30 Category 2

  20. Having a variety in genetics occurs in Mitosis Meiosis 40 Category 2

  21. Having a variety in genetics occurs in Meiosis 40 Category 2

  22. Which will increase the chances of a species surviving changing environmental conditions? Sexual reproduction Asexual reproduction 50 Category 2

  23. Which will increase the chances of a species surviving changing environmental conditions? Sexual reproduction 50 Category 2

  24. Category 3 questions follow

  25. Which of these does not describe Meiosis? It produces haploid cells It produces 4 sperm cells It produces 4 egg cells 10 Category 3

  26. Which of these does not describe Meiosis? It produces haploid cells It produces 4 sperm cells It produces 4 egg cells- It only produces 1 viable egg cell 10 Category 3

  27. Describe what is produced by oogenesis. 20 Category 3

  28. Describe what is produced by oogenesis. 1 haploid egg cell 20 Category 3

  29. Describe Crossing Over and its affects. 30 Category 3

  30. Describe Crossing Over and its affects. the tips of chromosomes touch and exchange places on the same chromosome It produces new DNA code in the cell 30 Category 3

  31. Catagorize these as Haploid or diploid Sex cells Zygote ½ the number of chromosomes Body cells Pollen cells Skin cells 40 Category 3

  32. Catagorizethese as Haploid or diploid Sex cells- Haploid Zygote- Diploid ½ the number of chromosomes-Haploid Body cells - Diploid Pollen cells- Haploid Skin cells Diploid 40 Category 3

  33. How is prophase 1 of meiosis different from prophase of mitosis? (hint- type of chromosome) 50 Category 3

  34. How is prophase 1 of meiosis different from prophase of mitosis? Prophase has sister chromatids Prophase I had Tetrads 50 Category 3
