How many scientific names do all plants or animals have?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

The correct response is two. Each plant or animal is assigned a scientific name consisting of two parts, which follow the system of binomial nomenclature developed by Carl Linnaeus. The first part of the name represents the genus, while the second part indicates the specific species within that genus. This two-part name allows for a standardized way to identify and classify organisms, reducing confusion that might arise from local common names. While one might think that only one name is assigned, this is misleading because it does not capture the full classification process. There could be instances where additional descriptive terms or identifiers are used, but these do not constitute a part of the formal scientific name as defined in binomial nomenclature. The options indicating three or four names could refer to broader classifications or additional descriptors that scientists might use in different contexts, but they do not reflect the actual naming convention for identification, which is strictly the two-part system.
