Definition: Binomial Nomenclature
Binomial nomenclature is a system of naming species of living organisms using two Latinised names.
CBSE: Class 12
Key Points: Binomial Nomenclature
- Binomial nomenclature is a system of naming organisms using two Latinised names, developed by Carl Linnaeus.
- The first name is the genus (generic name), written with a capital letter.
- The second name is the species (specific epithet), written in small letters.
- The scientific name is written in italics or underlined, e.g., Homo sapiens.
- This system provides a universal and standard naming method, avoiding confusion from common names and showing relationships among organisms.
