Presentation Transcript

  1. Cell Division

  2. Cell Division Chromosomes Function/Role Not dividing - Interphase Cell divides Comparison of Mitosis & Meiosis

  3. Chromosomes Haploid (n): one set of chromosome in nuclei Diploid (n): two sets of chromosomes are present in nuclei

  4. Function/Role Mitosis

  5. Mitosis Asexual reproduction Gamete formation in flowering plants Cell replacement

  6. Function/Role Mitosis Meiosis

  7. Meiosis Genetic variation Sexual reproduction Spore formation: e.g. flowering plants Gamete formation in animals, e.g. egg and sperm

  8. Function/Role Mitosis Meiosis

  9. Not dividing - Interphase Proteins are made Cell grows Organelles are made DNA replication

  10. Cell divides Mitosis

  11. Mitosis Prophase Metaphase Anaphase Telophase Cancer

  12. Cancer Biological agents - viruses Physical - X-rays, UV light Environmental - cigarette smoke, benzene

  13. Mitosis Prophase Metaphase Anaphase Telophase Cancer

  14. Cell divides Mitosis Meiosis

  15. Meiosis Location in humans

  16. Location in humans Testes - sperm, haploid male gametes, Ovary - egg, haploid female gametes

  17. Meiosis Location in humans Location in flowering plants

  18. Location in flowering plants Anther of the stamen - haploid male spores Ovule of ovary - haploid female spores

  19. Meiosis Location in humans Location in flowering plants

  20. Cell divides Mitosis Meiosis

  21. Comparison of Mitosis & Meiosis Meiosis

  22. Meiosis Not identical daughter cells

  23. Not identical daughter cells diploid organisms only 2n

  24. 2n n n n n

  25. Not identical daughter cells diploid organisms only 2n

  26. Meiosis Not identical daughter cells

  27. Comparison of Mitosis & Meiosis Meiosis Mitosis

  28. Mitosis Identical daughter cels

  29. Identical daughter cels Both diploid and haploid organisms n - 2 x n 2n - 2 x 2n

  30. Mitosis Identical daughter cels

  31. Comparison of Mitosis & Meiosis Meiosis Mitosis
