1. MITOSIS

2. Review Which cells use Mitosis? How many cells does Mitosis create?
All but the sex cells, muscle and nerve cells
For example: skin, cheek, plant & cells
How many cells does Mitosis create?
2 daughter cells
Are the cells diploid or haploid?
Diploid because have two pairs of chromosomes

3. Stages of Mitosis

4. Mitosis

5. Interphase Takes up the majority of the cell Cycle time
During Interphase most of the cells life activities are taking place:
Growth
Metabolism (Breakdown of food)
Chromosomes are duplicated
Growth and final preparations for division

6. Mitosis The last part of the cell cycle is called Mitosis
Mitosis includes the last 4 phases of the cell Cycle
Prophase
Metaphase
Anaphase
Telophase

7. Prophase Longest phase of mitosis The nucleus begins to disappear
Chromatin coils up to form Sister Chromotids
The sister chromatids are identical to the parent cells DNA
The halves are connected by a Centromere

8. Prophase Cont 2 Centrioles appear and migrate to the edges of the cell
Spindle fibers begin to form between the Centrioles and help pull apart the sister chromatids

9. Metaphase The 2nd and shortest phase of mitosis
The Chromosomes attach to the spindle fibers by the centromeres
The chromosomes line up in the middle of the cell

10. Anaphase The 3rd phase of Mitosis
The sister chromotids begin to break apart at the centromeres
Chromatids move towards the centrioles

11. Telophase The 4th phase of mitosis
The chromatids reach the edges of the cell
Two new nuclei reform around separated chromatids
The cell begins to uncoil the chromosomes
The uncoiled chromosomes then begin telling the cell what to do- This is the end of Mitosis
The plasma membrane begins to separate into 2 cells (This is the beginning
of Cytokinesis)
