1. Cell Division
Cell Division is the division of a cell into two daughter cells with the same genetic material.

2. Cell Division Living cells store critical information in DNA.
As a cell grows, that information is used to build the molecules needed for cell growth.
As size increases, the demands on that information grow as well. If a cell were to grow without limit, an “information crisis” would occur.

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

4. Cell Division
Meiosis (Sexual) is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell

5. Cell Division Meiosis

6. Cell Division Prophase I
Chromosomes condense, and the nuclear envelope breaks down

7. Cell Division
Metaphase I – Pairs of homologous chromosomes move to the equator of the cell

8. Cell Division
Anaphase I – Homologous chromosomes move to the opposite poles of the cell

9. Cell Division
Telophase I – Chromosomes gather at the poles of the cells, the cytoplasm divides

10. Cell Division
Prophase II - A new spindle forms around the chromosomes

11. Cell Division
Metaphase II – Chromosomes line up at the equator

12. Cell Division
Anaphase II – Centromeres divides, chromatids move to the opposite poles of the cells.

13. Cell Division
Telophase II – A nuclear envelope forms around each set of chromosomes, the cytoplasm divides
