Answers

Answer:

Scientific name of a plant is represented by the : Name of the Genus, Name of the Species and Name of the sub-species.

Explanation:

Genus - It is the hierarchical taxonomic classification of living organisms which is positioned below the Family but above the Species.
Species - It is the hierarchical taxonomic classification of living organisms which is positioned below the Genus and above the Sub-species. The individuals belonging to a particular species can interbreed among themselves.
Sub-species - It can be defined as the different populations of the same species which may occupy isolated and unrelated habitats and may vary in different characters.

Taking the example of pea plant,
Name of the Genus - Pisum.
Name of the species - sativum.
Name of sub-species -sativum(garden pea),elatius(wild pea).
