  3. Asexual reproduction – this kind of reproduction involves a single parent to produce young ones. In asexual reproduction, the individual grows and splits into two and this process continues. Examples are binary fission, vegetative reproduction (as in potato, cassava, yam etc.) and so on
  4. Sexual reproduction – this is the kind of reproduction which involves two sexes. The male produces a sex cell and the female does that too. This is the most common means of reproduction in animals but is also found in plants.

THE MALE REPRODUCTIVE SYSTEM

The male reproductive system is made up of organs found both outside and inside the body. Such as the penis, scrotum, testes etc. The male sex cell is called the sperm. This is what fusses with the female sex cell at fertilization.
