Mitosis from FTCC

  1. 1. Asexual Reproduction Mitosis Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals? 1 1
  2. 2. How do little elephants grow up to be BIG elephants?
  3. 3. The process of asexual reproduction begins after a sperm fertilizes an egg.
  4. 4. Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun. Cell that reproduce by asexual reproduction reproduce constantly.
  5. 5. Animated Mitosis Cycle http://www.cellsalive.com/mitosis.htm • Interphase • Prophase • Metaphase • Anaphase • Telophase & Cytokinesis
  6. 6. • Chromosomes are copied (# doubles) • Chromosomes appear as threadlike coils (chromatin) at the start, but each chromosome and its copy(sister chromosome) change to sister chromatids at end of this phase CELL Nucleus MEMBRANE Cytoplasm
  7. 7. Unreplicated vs. replicated chromosome During which part of the Cell Cycle does replication of DNA occur . . . Interphase, or Cell Division (Mitosis or Meiosis)?
  8. 8. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
  9. 9. • Mitosis begins (cell begins to divide) • Centrioles (or poles) appear and begin to move to opposite end of the cell. • Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers
  10. 10. Animal Cell Plant Cell Spindle fibers Centrioles Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
  11. 11. • Chromatids (or pairs of chromosomes) attach to the spindle fibers. Centrioles Spindle fibers
  12. 12. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
  13. 13. • Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers
  14. 14. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
  15. 15. • Two new nuclei form. • Chromosomes appear as chromatin (threads rather than rods). • Mitosis ends. Nuclei Nuclei Chromatin
  16. 16. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
  17. 17. • Cell membrane moves inward to create two identical daughter cells – each with its own nucleus with identical chromosomes. • Daughter cells are IDENTICAL to the original parent cell.

  19. 19. Plant Mitosis -- Review Interphase Prophase Metaphase Anaphase Telophase Interphase
