Sexual Reproduction

  1. 1. Sexual Reproduction By- Justin Ehrenpreis
  2. 2. Production of sex cells is…… <ul><li>Gametes </li></ul>
  3. 3. Sex cell fuse by………… <ul><li>Fertilization </li></ul>
  4. 4. Produces an egg cell……. <ul><li>Zygote </li></ul>
  5. 5. What involves 2 parents? <ul><li>Sexual Reproduction </li></ul>
  6. 6. Both parents contribute………… <ul><li>A Gamete </li></ul>
  7. 7. Gametes contain………………. <ul><li>Genetic information giving by…… </li></ul><ul><li>Offspring obtained…… </li></ul><ul><li>equally </li></ul>
  8. 8. Gametes are formed in …….. <ul><li>Reproductive structures called…. </li></ul><ul><li>gonads </li></ul>
  9. 9. Gametes are……………. <ul><li>Sex cells </li></ul>
  10. 10. Males cells called………….. <ul><li>Sperm </li></ul>
  11. 11. Females cells called………….. <ul><li>Ovum or……. </li></ul><ul><li>egg </li></ul>
  12. 12. Gametogenesis is <ul><li>A process that gametes are produced by….. </li></ul><ul><li>Meiosis </li></ul><ul><li>That happens in the………. </li></ul><ul><li>Gonades </li></ul>
  13. 13. Meiosis is…………….. <ul><li>Reduction division that create gametes </li></ul>
  14. 14. Fertilization is……….. <ul><li>Fusion of one sperm nuclei with one ova (egg) nuclei, producing a ………………… </li></ul><ul><li>Zygote </li></ul>
  15. 15. Haploid or Monoplaoid represents……………. <ul><li>A gamete which has half of the # of chromosomes necessary. </li></ul>
  16. 16. Once 2 gametes fuse together they……… <ul><li>Form a zygote that is a…… </li></ul><ul><li>Diploid </li></ul>
  17. 17. Diploid has………….. <ul><li>2 joined chromosomes which is………. </li></ul><ul><li>A set </li></ul>
  18. 18. Meiosis occurs in……… <ul><li>Diploid cells </li></ul>
  19. 19. Meiosis chromosomes duplicate……… <ul><li>Once through 2 successive divisions, 4 haploid cells, with half the chromosome # of ……. </li></ul><ul><li>Parental cell </li></ul>
  20. 20. Meiosis occurs only in….. <ul><li>Sexual reproducing organisms </li></ul>
  21. 21. Depending on organism it may produce………………. <ul><li>Haploid gametes, that……………… </li></ul><ul><li>Do not……. </li></ul><ul><li>Divide further but…… </li></ul><ul><li>Fuse to produce a……. </li></ul><ul><li>Diploid zygote </li></ul><ul><li>May produce….. </li></ul><ul><li>Haploid spores. </li></ul>
  22. 22. Haploid spores ……. <ul><li>Divide by….. </li></ul><ul><li>Mitotic cell cycles and produce…… </li></ul><ul><li>Unicellular or multi cellular organisms. </li></ul>
  23. 23. Animas products of meiosis is the……………………… <ul><li>Gametes. </li></ul>
  24. 24. Meiosis consist of…………… <ul><li>2 nuclear divisions </li></ul><ul><li>Meiosis1 and 2 </li></ul>
  25. 25. Crossing-over is………. <ul><li>A process that can give rise to genetic recombination. </li></ul>
  26. 26. Nucleolus disappears during……………. <ul><li>Prophase 1 </li></ul>
  27. 27. The key difference between mitosis and meiosis is…….. <ul><li>That sister chromatids remain joined after Metaphase in Meiosis 1, whereas in mitosis they separate. </li></ul>
  28. 28. Centrioles are in………… <ul><li>Opposite poles. </li></ul>
  29. 29. Cytokinessis is <ul><li>Separation. </li></ul>
  30. 30. Meiosis has……. <ul><li>4 cells </li></ul>
  31. 31. Mitosis has……… <ul><li>2 cells </li></ul>
  32. 32. Chromosome do not………. <ul><li>Replicate again in Meiosis 2 Prophase 2 </li></ul>
  33. 33. Meiosis 2 Telophase 2 <ul><li>The making of 4 daughter cells </li></ul>
