1. Cell Division - Mitosis

2. Cell Division
Cell division is when a cell duplicates itself, making two cells out of one
Cell division is how organisms can grow and develop

3. Cell Division
There are two types of cell division
Mitosis
Meiosis

4. Mitosis
Mitosis is a form of cell division in which a cell’s nucleus and nuclear material divide to create two identical daughter cells
Only somatic cells undergo mitosis
Somatic cells are all the cells in your body that are not sex cells (eggs and sperm)

5. Stages of Mitosis Mitosis is divided into stages: Interphase Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

6. Interphase In Interphase…
Cell grows and carries out normal cell processes
DNA replicates (copies itself)

7. Mitosis - Prophase In Prophase… Nuclear membrane disintegrates
DNA condenses into chromosomes
Mitotic spindles begin to form between the poles (opposite ends) of the cell

8. Mitosis - Metaphase In Metaphase…
Chromosomes attach to mitotic spindles and align along the equator (middle)

9. Mitosis - Anaphase In Anaphase…
Mitotic spindles shorten, moving chromosome strands to opposite poles

10. Mitosis - Telophase In Telophase… Chromosomes reach poles of cell
Nuclear envelope re-forms
Almost two separate cells but the cytoplasm of both cells is attached still

11. Cytokinesis
In cytokinesis, the cytoplasm is divided to create two distinct daughter cells
In animal cells, a cleavage furrow forms at the equator of the cell and pinches inward until the cell divides in two
