Select the correctly written botanical/zoological name.

Detailed Solution: Question 2

Some important rules of binomial nomenclature are given as following:
(i) Biological names are either derived from Latin language or are Latinised.
(ii) The first word in a biological name represents the genus while the second word represents the species.
(iii) Both the words, in a biological name, when handwritten, are separately underlined, or printed in italics to indicate their Latin origin.
(iv) The generic epithet starts with a capital letter while, the specific epithet starts with a small letter. It can be illustrated with the example of Homo sapiens, Pisum sativum, Panthera tigris, Mangifera indica, etc.
(v) Name of the author appears after the specific epithet i.e., at the end of the biological name and is written in an abbreviated form, e.g., Mangifera indica line. It indicates that this species was first described by Linnaeus.

Topic in NCERT: Taxonomy and nomenclature

Line in NCERT: "let us consider mangifera indica, solanum tuberosum (potato) and panthera leo (lion). all the three names, indica, tuberosum and leo, represent the specific epithets, while the first words mangifera, solanum and panthera are genera and represents another higher level of taxon or category."

Lower categories (like Genus, Species) are more specific and have clearer relationships.

Thus, the correct answer is: B: Greater, difficulty.

Topic in NCERT: Taxonomic categories

Line in NCERT: "higher the category, greater is the difficulty of determining the relationship to other taxa at the same level."

Assertion (A): Systematics is primarily concerned with the classification and naming of organisms based on their evolutionary relationships.

Reason (R): Systematics encompasses only the identification of organisms without regard to their evolutionary history.

Detailed Solution: Question 9

  • The Assertion is true because systematics indeed focuses on the classification and naming of organisms while considering their evolutionary relationships.
  • The Reason is false as it states that systematics does not regard evolutionary history, which contradicts the fundamental principles of systematics.
  • Since the Assertion is true and the Reason is false, the correct option is Option C.

    Line in NCERT: Human beings were, since long, not only interested in knowing more about different kinds of organisms and their diversities, but also the relationships among them. This branch of study was referred to as systematics. The word systematics is derived from the Latin word ‘systema’ which means systematic arrangement of organisms. Linnaeus used Systema Naturae as the title of his publication. The scope of systematics was later enlarged to include identification, nomenclature and classification. Systematics takes into account evolutionary relationships between organisms
