What is key??
How is it helpful in identification, classification and nomenclature???
Dear student
A key is a sequence of contrasting characteristics, in which each stage presents descriptions of two contrasting characters with a direction to another stage in the key, until the species is identified. It helps in identification by helping us choosing a characteristic sequence wise that matches with are sample and then giving it a name at the end.
