1. How do baby animals grow to be adults?

2. Why do animals shed their skin?

3. Cells divide for three purposes:
Organisms grow because cell division increases the total number of cells.
Each day, cells in your body wear out or become damaged and need to be replaced.
Asexual reproduction

4. The Cell Cycle - Mitosis
A cell grows, prepares for division, and then divides into two new cells. These two new cells, called daughter cells, are identical to the parent cell because they have the same DNA as the parent cell.

5. 3 stages of the Cell Cycle:
Interphase
Mitosis
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

6. Interphase Cell spends most of its life in this phase
The cell grows to its full size
DNA is copied in the nucleus of the cell
Cell prepares to divide

8. Interphase

9. Prophase 1st and longest phase of Mitosis Chromosomes become visible
Centrioles separate and move to opposite ends of cell
Spindle fibers appear
Nuclear membrane disappears

10. Prophase

11. Metaphase 2nd and shortest phase of Mitosis
Chromosomes attach to spindle fibers in center of cell

12. Metaphase

13. Anaphase 3rd phase of Mitosis
Centromeres split apart and chromatids separate from each other.
Chromosomes move to opposite poles

14. Anaphase

15. Telophase 4th and last phase of Mitosis
Chromosomes reach opposite poles of cell
Chromatids unwind back into chromatin
Nuclear membranes begins to form around the chromatin at each end
Spindle fibers disappear

16. Telophase

17. Cytokinesis New cell membrane forms between two nuclei.
The cell splits into two new cells – each with identical chromosomes.

18. Cytokinesis
