Reproductive Systems

Source: Biology 12, Ch 17, 17.1

📘Easy summary

Reproduction is the ability of an organism to produce new offspring of its own type. Functions of the reproductive systems: production of gametes and their preparation for fertilization; the male system delivers gametes to the female system, and the female system nourishes the fertilized egg and provides an environment for its development into a baby. The reproductive system differs from other systems in two ways: it is quite different in male and female, and it does not become functional until puberty, whereas other systems work since or shortly after birth.

⭐Key points

  • Makes and prepares gametes.
  • Female nourishes the embryo.
  • Functional only at puberty.
