Let’s Start .
1. Read the text carefully to comprehend what reproduction is
Reproduction is the biological process by which existing organisms create new individual organisms. Every existing plant, animal or other living
organism is the result of biological reproduction, and all living things reproduce in some way. The many known methods of reproduction are
generally placed into one of two classifications, sexual and asexual reproduction.
Sexual reproduction, which includes human sexual reproduction and most other animal reproduction, requires the participation of two individuals
of the opposite sex. During sexual reproduction, an embryo is formed when an egg carried by the female is fertilized by the male as during human
reproduction.
The division of a bacterial cell into two daughter cells is an example of asexual reproduction. Typically, more complex organisms practice sexual
reproduction, while single-celled and other less complex organisms practice asexual reproduction. Most plants also have the ability to reproduce utilizing
asexual reproduction.
Organisms that reproduce via asexual reproduction generally produce significantly more offspring than animals and other organisms that reproduce
by way of sexual reproduction. However, since it relies on self-mutation, 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.
