    Mitosis review

    Plant mitosis and interphase in Allium (onion) root-tip cells:
    Look for mitotic cells in the meristem (behind the root cap) of Allium (onion) root tip.

    Determining the relative time length of the stages of mitosis in Allium: p. 135
    Typical plant cell cycle is about 800 (not 80) minutes.

    1. Randomly select an area within the meristem on the slide.
    2. Record the number of cell in each stage.
    3. Do three trials.
    4. Estimate the length of time for each stage,
