Read each question carefully and answer to the best of your ability. This worksheet will test your understanding of binomial nomenclature and how scientists classify living organisms.
Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. This system was popularized by Carl Linnaeus. The first part of the name identifies the genus to which the species belongs, while the second part identifies the species within the genus. For example, humans are known as Homo sapiens.
