Test: What is Living (NCERT) - NEET MCQ

Biological names are Latinized and written in Italics. The generic epithet starts with capital letter while the second component specific epithet starts with small letter. Here the binomial nomenclature of Lion is Panthera leo but not Panthera Leo. Also, in Panthera Tigress the second component is written in capital letter which means that Panthera Tigress is not the answer. And in Panthera Lion the word Lion is not derived from Latin which reflects that Panthera Lion is also not the answer.

Line in NCERT: "Lion (Panthera leo), leopard (P. pardus) and tiger (P. tigris) with several common features, are all species of the genus Panthera."

Generic name and specific epithet are the two parts of a binomial nomenclature. A generic name specifies the genus of an organism and the specific epithet describes the species to which it belongs to.

Line in NCERT: "Each name has two components the Generic name and the specific epithet."

Animals are named by the principles and criteria provided in International Code for Zoological Nomenclature (ICZN). There is a separate set of rules for the naming of plants called International Code of Botanical Nomenclature (ICBN).

Line in NCERT: "Animal taxonomists have evolved International Code of Zoological Nomenclature (ICZN)."

To determine the taxonomic category containing organisms least similar to one another:

- Class: Contains organisms sharing several characteristics but differing in others.
- Genus: Groups species with more similarities than those in different genera.
- Family: Shows more variation than genera but less than classes.
- Species: Individuals within a species are most alike.

Correct Answer: A: Class - Organisms in the same class have greater differences compared to those in the same genus, family, or species.

Line in NCERT: "Families are characterised on the basis of both vegetative and reproductive features of plant species."

The correct answer is A: step-wise arrangement of all categories for classification of plants and animals.

- Taxonomic hierarchy organizes living organisms into a structured order.
- It starts with the broadest category (Domain) and narrows down to the specific species.
- The hierarchy includes Kingdom, Phylum, Class, Order, Family, Genus, and Species.
- This systematic arrangement aids in understanding relationships among different organisms.
- It provides a framework for scientists to classify and study the diversity of life forms.

Line in NCERT: "All the categories constitute a taxonomic hierarchy."
