Mitosis

  1. 1. Mitosis: Asexual Cell Reproduction
  2. 2. Mitosis : Making 2 new cells from a single original. Genetically Identical
  3. 3. 5 Stages <ul><li>Interphase </li></ul><ul><li>Prophase </li></ul><ul><li>Metaphase </li></ul><ul><li>Anaphase </li></ul><ul><li>Telophase </li></ul><ul><li>IPMAT </li></ul>
  4. 4. Interphase <ul><li>“ I n between Cell Divisions” </li></ul><ul><li>Most of the cell life cycle </li></ul><ul><li>Growth and other life processes </li></ul><ul><li>DNA duplicates </li></ul>
  5. 5. Prophase <ul><li>“ P repare to Divide” </li></ul><ul><li>Chromatin condenses to form chromosomes </li></ul><ul><li>Centrioles migrate to opposite poles </li></ul><ul><li>Spindle fibers form and attach near centromere </li></ul><ul><li>Nuclear envelope disappears </li></ul>
  6. 6. Metaphase <ul><li>“ Chromosomes in the M iddle” </li></ul><ul><li>Chromosomes line up across the middle </li></ul><ul><li>Spindle fibers connect centromere to centriole </li></ul>
  7. 7. Anaphase <ul><li>“ Chromosomes A part” </li></ul><ul><li>Sister chromosomes separate at centromere </li></ul><ul><li>Move to opposite poles </li></ul>
  8. 9. Telophase <ul><li>“ End with t wo daughter cells” </li></ul><ul><li>Cytokinesis – division of the cytoplasm </li></ul><ul><ul><li>Pinching in with animal cell </li></ul></ul><ul><ul><li>Cell plate (new cell wall) forms in plant cell </li></ul></ul><ul><li>Chromatin separates and returns to loose state </li></ul>
