So everybody knows exactly what plant, insect or animal you are taking about.
Only one plant is called Capsella bursa-pastoris. I might call this plant 'shepherd's purse' but somebody else might call it something different. Common names can vary from country to country or person to person.
The scientific name is exact.
Only Latin for the binomial scientific name, but in colloquial names some parts are taken from Greek as well.
Latin and Greek
The two levels of classification used in scientific naming are genus and species. This system is known as binomial nomenclature, with organisms being identified by their genus and species names.

Scientific names are based on Latin and Greek. These languages are used because they are considered universal and do not change over time, ensuring consistency in the names of organisms across different languages and regions.
Scientific names of all living creatures are in Latin. Occasionally a Greek word will be used, or a "latinized" word will be created if none exists. An example of this is the scientific name for a particular owl mite, named "Strigophilus garylarsonii,'' apparently named after the creator of the "Far Side" comic strip, Gary Larson. The scientific name consists of the genus and species, the last two categories in the taxonomical classification of the living organism in question.
Scientific Names are used to identify things by their Family and Kingdom. One part refers to the general "where does this fall" and the other refers to "this is what it is"
Latin or Greek
You can find scientific notation being used wherever numbers are very large or very small.
