  1. what are the four phases of mitosis
    • prophase
    • metaphase
    • anaphase
    • telephase
  2. what is the longest stage of mitosis
  3. describe what happens to the chromatin, nuclear membrane & nucleolous, and the spindle during prophase
    • chromatin: condenses into chromosomes
    • nuclear membrane & nucleolous: disappear
    • spindle: forms
  4. what creates the spindle?
    protein fibers form between the two centrioles
  5. what kind of structure is a spindle
  6. what will the spindle do during mitosis
    move the chromosomes
  7. what happens during metaphase
    the chromosomes attach to the spindle and move to the equator of the cell
  8. what happens during anaphase
    the centromeres divide and the sister chromatids move to the opposite poles
  9. what happens during telephase
    new nuclear membranes form around each set of chromosomes, the nucleolus reappears and the spindle breaks down
  10. describe animal cytokinesis
    the cell membrane is drawn inward until the cytoplasm is divided into 2 nearly equal parts
  11. describe plant cytokinesis
    a cell plate forms between the 2 nuclei and divides the cell into 2 parts. the cell plate becomes the new cell wall
