The document summarizes the male and female reproductive systems. It explains that the female system produces eggs and allows for fertilization and embryo development. The male system produces and stores sperm. Fertilization occurs when a sperm enters an egg to form a zygote, which develops into an embryo and fetus over a typical 9 month pregnancy period. The placenta provides nutrients to the developing baby until birth.

and dies if it is not fertilised.

4.  A sperm from a man and an ovum/egg
from a woman are necessary to create
descendents similar to them.
 The sperm enters the egg and
fertilises it. They form a new cell called
a zygote. When it consists of about
100 cells, it is called an embryo.
