  1. The Cell Cycle & Cell Division

  2. The Cell Cycle http://www.nobel.se/medicine/laureates/2001/press.html

  3. Animated Cycle http://www.cellsalive.com/cell_cycle.htm

  4. MITOSIS

  5. Mitosis The process of cell division which results in the production of two daughter cells from a single parent cell. The daughter cells are identical to one another and to the original parent cell.

  6. Mitosis can be divided into stages • Interphase • Prophase • Metaphase • Anaphase • Telophase & Cytokinesis

  7. Animal Cell DNA replicated Organelles replicated Cell increases in size Plant Cell DNA replicated Organelles replicated Cell increases in size InterphaseThe cell prepares for division

  8. Interphase Plant Cell Animal Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm

  9. Animal Cell Packages DNA into chromosomes Plant cell Packages DNA into chromosomes ProphaseThe cell prepares for nuclear division

  10. Prophase Plant Cell Animal Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm

  11. Animal Cell Chromosomes line up at the center of the cell Spindle fibers attach from daughter cells to chromosomes at the centromere Plant Cell Chromosomes line up at the center of the cell Spindle fibers attach from daughter cells to chromosomes at the centromere MetaphaseThe cell prepares chromosomes for division

  12. Metaphase Plant Cell Animal Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm

  13. Animal Cell Spindle fibers pull chromosomes apart ½ of each chromosome (called chromotid) moves to each daughter cell Plant Cell Spindle fibers pull chromosomes apart ½ of each chromosome (called chromotid) moves to each daughter cell AnaphaseThe chromosomes divide

  14. Anaphase Plant Cell Animal Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm

  15. TelophaseThe cytoplasm divides Animal Cell DNA spreads out 2 nuclei form Cell membrane pinches in to form the 2 new daughter cells Plant Cell DNA spreads out 2 nuclei form New cell wall forms between to nuclei to form the 2 new daughter cells

  16. Telophase Plant Cell Animal Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
