Chapter Outline:

1. Cell are of three types : body cells , germ cells and sex cells

2. A body cell divides by mitosis producing 2 body cells with the same genetic material

3. A germ cell divides by meiosis producing 4 sex cells with half the genetic material

4. steps of mitosis and meiosis : (go to links and check there the animation of cell division)

5. males produces sex cells called sperm from the division of a germ cell by meiosis while females produces sex cells called eggs from the division of a germ cell by meiosis

6. differences between eggs and sperms

7. Aging : causes and effect

8. Cancer : causes and effect
