  • Mitosis Write-Up

    Mitosis: (onion roots) Root cells are good for observing mitosis; this is because they're in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once, also allowing us to examine the different stages of mitosis. Stages: ...

  • Mitosis

    Introduction: Mitosis is one of the parts of the cell cycle. The cell cycle, as the phrase already suggests, is the life cycle of a cell. It is the way all cells live then almost reproduce to produce new cells that are genetically identical to all the other cells around it in the that same area of tissue. ...
