Scientific classification is how scientists catagorize and name plants and animals.
In order to effectively study plants and animals, all scientists need to use the same names. Using the same names keeps scientists from getting confused about what species is being referred to. The Linnaean taxonomic system is quite useful as a classification system. Not only does it provide official names for every plant and animal, it also helps scientists understand how objects are related to one another. The Linnaean system is based on a series of nested categories.
