Mitosis, Meiosis, and Sexual Reproduction
Watch these videos to review the steps of mitosis and meiosis. Notice the additional division in meiosis that leads to genetic variability. How would you describe stages of meiosis and how cells are produced? Can you explain why meiosis is needed for sexual reproduction? What cells are involved in fertilization? How does fertilization occur?
After you have watched the videos, you should be able to distinguish between somatic cell and gamete, distinguish between haploid and diploid cells, list the phases of meiosis I and meiosis II, describe the events of each phase, and illustrate the phases of meiosis.
