Reproduction means to reproduce. It is a
organic process by which an organism reproduces an offspring who is biologically almost like the organism.It is the main feature of life on earth. There are basically two types of reproduction:Asexual Reproduction,Sexual Reproduction. Asexual reproduction does not involve the fusion of gametes, and therefore, the offsprings produced are genetically identical to the parent. The organisms produced by agamogenesis are less diverse in nature. This type of reproduction is practised widely by unicellular organisms. In sexual reproduction, male and female gametes form to produce an offspring. These gametes are either formed by the same individual or by different individuals of the opposite sex.This process is usually slow and complex compared to asexual reproduction. The organisms so produced are genetically diverse. Thus, they can evolve along with the changing climatic conditions. Humans and many multicellular organisms exhibit a sexual mode of reproduction. Animals reproduce sexually as well as asexually. Sexual reproduction involves the fusion of male and female gametes. This process is known as fertilization. Fertilization can be external or internal. External fertilization is the process in which the male sperm fertilizes the female egg outside the female’s body. On the contrary, in internal fertilization, the fusion of male and female gametes takes place inside the body of the female.Asexual reproduction involves reproduction processes such as binary fission, budding, fragmentation, etc. The organisms have no reproductive systems and therefore no formation ofmale and female gametes takes place.Thus we see how beneficial reproduction is to continue life on earth.
