The female gamete cell is called ovum or egg(It contains water,stored food and nucleus). Fusion of egg and sperm give rise to a single cell called ZYGOTE. ... These sperms then fertilise the egg inside the woman's body. The fertilisation which occuroutside the female body is called externalfertilisation.
Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
