What we have learnt
- Living organisms are classified to facilitate identification and study their diversity.
- Taxonomy involves nomenclature, identification, and classification of organisms into various hierarchical categories.
- Scientific names are based on universal codes, ensuring that each organism has a unique name recognized globally.
Key Concepts
- -- Biodiversity
- The variety and variability of life forms, including the different species of plants, animals, and microorganisms.
- -- Nomenclature
- The system of assigning names to organisms in a standardized manner, ensuring uniformity and clarity in communication.
- -- Taxonomy
- The science of classification, which groups living organisms based on common characteristics and establishes their names.
- -- Binomial Nomenclature
- A two-part naming system for organisms, wherein the first part represents the genus and the second part signifies the specific epithet.
- -- Taxonomic Hierarchy
- A system of organizing biological classification into ranks or categories, ranging from species to kingdom.
