Mitosis
Cell division

2. Cell division
All complex organisms originated from a single fertilized egg.
Every cell in your body started here, through cell division the numbers are increased
Cell then specialize and change into their various roles

3. Mitosis Cell division occurs in a series of stages, or mitosis.
Mitosis is the process by which new body cell are produced for:
Growth
Replacing damaged or old cells.
Cell division occurs in a series of stages, or mitosis.

4. Parent cell
Chromosomes are copied and double in number
Chromosomes now split
2 daughter cells identical to original

5. Animated Mitosis Cycle
Interphase
Prophase
Metaphase
Anaphase
Telophase & Cytokinesis

6. Interphase occurs before mitosis begins
Chromosomes are copied (# doubles)
Chromosomes appear as threadlike coils (chromatin) at the start, but each chromosome and its copy(sister chromosome) change to sister chromatids at end of this phase

8. Prophase 1st step in Mitosis
Mitosis begins (cell begins to divide)
Centrioles (or poles) appear and begin to move to opposite end of the cell.
Spindle fibers form between the poles.

Sister chromatids
Spindle fibers

Photographs from:

10. Metaphase 2nd step in Mitosis
Chromatids (or pairs of chromosomes) attach to the spindle fibers.

Photographs from:

12. Anaphase 3rd step in Mitosis
Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell.

Spindle fibers

13. Anaphase Plant Cell Animal Cell
Photographs from:

14. Telophase 4th step in Mitosis
Two new nuclei form.
Chromosomes appear as chromatin (threads rather than rods).
Mitosis ends.

15. Telophase Plant Cell Animal Cell
Photographs from:

16. Cytokinesis occurs after mitosis
Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.

23. Mitosis
All daughter cells contain the same genetic information from the original parent cell from which it was copied.
Every different type cell in your body contains the same genes, but only some act to make the cells specialize – e.g. into nerve or muscle tissue.
