♦ Relevant knowledge

In mammals that have babies (including humans and other mammals) the ovum gets fertilized in the female, and then the embryo is developed within the uterus. It receives the nutrients directly. The mother’s body.

Human Ovum is created from zygote stem cells which are contained within an ovary. Every cell divides several times, resulting in a number of smaller cells known as oocytes.

Sperm are produced by testes. Each sperm is a carrier of 23 different chromosomes i.e. 50% of the DNA needed to make up a human (23 pair) thus it is known as a the haploid cell. Human sperm cells are comprised of a head that is 5µm (5 millimeters) long, and an elongated tail of 50µm. Because of its whip-shaped tail the sperm can travel between 1-3 millimeters/minute.
