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
