Expert Answer:

  • Fertilisation is the process of the male gamete (sperm) and the female gamete (ovum) to form a zygote.
  • During copulation, the sperms are released into the vagina of female near the cervix of the uterus.
  • These sperms actively pass through the passage of the cervix into the uterine cavity.
  • Of the millions of sperms released into the vagina, very few are able to reach the upper parts of the oviducts. The rest die on the way and are absorbed.
  • A single sperm moves towards the egg cell.
  • Mitochondria of the sperm provide energy for its movement towards the egg cell.
  • Acrosome of the sperm releases an enzyme which digests the membrane of the egg cell.
  • The head of the sperm enters the egg cell.
  • The nuclei of the sperm and the egg cells fuse to form the zygote.
