introduction to reproduction
... Living things can reproduce in two different ways: (1) Sexually through the union or mating of male and female; or (2) Asexually which does not involve the union of male and female. If you take a cutting of a plant and place it in soil, it will grow into a new plant. Gardeners often use this method ...

Fertilisation
Fertilisation (also known as conception, fecundation and syngamy) is the fusion of gametes to initiate the development of a new individual organism. In animals, the process involves the fusion of an ovum with a sperm, which first creates a zygote and then leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilisation, or outside (external fertilisation). The cycle of fertilisation and development of new individuals is called sexual reproduction.
