Mitosis

  1. 1. Mitosis <ul><li>Objectives </li></ul><ul><li>Explain why cell growth requires cell division. </li></ul><ul><li>Describe and label the stages of mitosis. </li></ul>
  2. 2. Why Cell division? <ul><li>It’s how we grow! </li></ul>
  3. 3. Why Cell division? <ul><li>It’s how we </li></ul><ul><li>Heal </li></ul><ul><li>Replace cells </li></ul>At least most of the time when you break
  4. 5. Prophase <ul><li>Chromosomes become very dense . </li></ul><ul><li>The nuclear envelope breaks down </li></ul><ul><li>The spindles form at opposite &quot;poles&quot; of the cell </li></ul>
  5. 6. Metaphase <ul><li>The spindle is fully develops </li></ul><ul><li>chromosomes align </li></ul>
  6. 7. Anaphase <ul><li>The sister chromatids (paired chromosomes) separate and begin moving to opposite poles of the cell </li></ul><ul><li>Spindle fibers not connected to chromatids lengthen and elongate the cell </li></ul>
  7. 8. Telophase <ul><li>The nuclei of the new cells form creating the daughter cells </li></ul>
  8. 9. Interphase <ul><li>The chromosomes are doubling in preparation for cell division </li></ul>
