In our biosphere which consists of living and non living organisms the living organisms have the continuity of life because they all have the capacity to reproduce.
Reproduction is the biological process by which existing organisms create new individual organisms of the same kind. It maintains the thread of life. Every existing plant, animal or other living organism is the result of biological reproduction. Do all organisms reproduce in the same way? The solution for this lies in this chapter.
The many known methods of reproduction are generally placed into one of two classifications, sexual and asexual reproduction.
Sexual reproduction, is seen in humans as well as in higher forms of animals. This requires the participation of two individuals of the opposite sex. During sexual reproduction, an egg carried by the female is fertilised by the sperm of the male and an embryo is formed.
Asexual reproduction takes place within the same individual. The division of a bacterial cell into two daughter cells is an example of asexual reproduction. The single-celled and other less complex organisms practice asexual reproduction. Most plants also have the ability to reproduce utilising asexual reproduction.
During asexual reproduction, organisms produce significantly more offspring than animals and other organisms that reproduce by way of sexual reproduction. However, since it relies on self-mutation for variation, organisms created through asexual reproduction are far more susceptible to disease and other genetic disorders. Sexual reproduction, on the other hand, produces offspring with much greater genetic variation and a much smaller vulnerability to disease.
