Presentation Transcript

  1. Onion Root-tip Mitosis

  2. Interphase Nucleolus Nucleus Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase Telophase

  3. Early Prophase Nuclear Membrane breaks down Chromosomes appear Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase Telophase

  4. Later Prophase Chromosomes organizing No Nucleus Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase Telophase

  5. Early Metaphase Spindle forms Chromosomes align along “equator” Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase Telophase

  6. Later Metaphase Chromosomes tighter on center Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase Telophase

  7. Anaphase Chromosomes separate Interphase Early Prophase Later Prophase Kinetochore fibers shorten Early Metaphase Later Metaphase Anaphase Telophase

  8. Telophase Nuclei re-form Early Middle Late Cell Plate (Cytokinesis) Interphase Early Prophase Later Prophase Early Metaphase Later Metaphase Anaphase
