What two components are necessary for the binomial classification of a plant?

1. Family and genus

2. Genus and specific epithet

3. Species and variety

4. Class and order

The correct answer is: Genus and specific epithet

The binomial classification system, also known as the Linnaean system, requires two key components to name and categorize a plant: the genus and the specific epithet. This combination creates a unique scientific name for each species, allowing for clear and consistent communication among scientists and horticulturists. The genus indicates the broader group to which the species belongs, while the specific epithet distinguishes the particular species within that genus. This systematic approach helps avoid confusion that can arise from common names, which may vary from one region to another. The emphasis on these two components is fundamental in taxonomy, ensuring that each plant species can be accurately identified and classified within the broader context of plant diversity.
