Assigning scientific name to living organisms is called nomenclature. According to this system all living things are given a scientific name, which consists of two parts.
i) First part of the name is genus. It is written in capital letter.
ii) Second part of the name is species. It is written in small letter.
For example the scientific name of frog is Rana tigrina, and scientific name of human
being is Homo sapiens.
Significance: -
Some plants may be known as difference common local names in different languages.
E.g. Turnip, Shaljam, Thippar and gongloo are the names of same plant. This
confusion can be avoided by giving each organism a scientific name which is standard
in all over the world.
