What is the primary purpose of using scientific names for plants?

• A. to standardize common names across languages
• B. to reflect the plant's origin
• C. to honor the discoverer
• D. to avoid confusion concerning the names of plants

Answer: (D)

Scientific names are used to avoid confusion in plant identification. Common names vary widely by language, region, and culture, and the same name can refer to different species while a single plant can have many different nicknames. The two-part scientific name (genus and species) provides a unique, universal label for each species, so botanists, horticulturists, and gardeners around the world can be sure they’re talking about the same plant. While some names may reflect origin or honor a discoverer, that’s not the main purpose—consistency and precision across languages and regions are.
