Cell division
Storyboard-Text
- Emma- Hey, Ava, do you know what cell division is and how it works?
- Ava- No, I don't know how it works.
- Let me tell you how cell division works.
- OK, I'm excited.
- -Cell division is the process by which a parent cell divides into two or more daughter cells.
- The cell division cycle, more commonly and simply known as the cell cycle.
- Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.
- In early prophase, the cell starts to break down some structures and build others up, setting the stage for division of the chromosomes.
- Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
- In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
- In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell.
- In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
