1. How do little elephants grow up to be BIG elephants?

2. Why do animals shed their skin?

3. Two types of reproduction: asexual and sexual
The answer is…..
Cell Reproduction!!
All living organisms have a life cycle! A life cycle begins with the organism’s formation, is followed by growth and development and finally ends in death.
Two types of reproduction: asexual and sexual

4. Three reasons why cells reproduce asexually
1.) Growth
2.) Repair
3.) Replacement

5. Mitosis
The process in which the nucleus divides to form two identical nuclei
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

6. Interphase Happens before mitosis begins
Chromosomes are copied (# doubles)

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

8. Metaphase 2nd step in Mitosis
Chromatids (or pairs of chromosomes) line up in the middle and attach to spindle fibers

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

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

11. Cytokinesis Occurs after mitosis
Cell membrane moves inward to create two daughter cells- each with its own nucleus and identical chromosomes.
