Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Wheat (Triticum aestivum) and Mango (Mangifera indica) are placed in the same Division, Angiospermae. Reason (R): Both Wheat and Mango belong to the same Class Monocotyledonae because both are flowering plants with two cotyledons. In the light of the above statements, choose the correct answer from the options given below:

Given below are two statements: Statement I: Biological names are generally in Greek and written in bold script irrespective of their origin. Statement II: The first word in a biological name denotes the specific epithet, while the second component denotes the genus. In the light of the above statements, choose the most appropriate answer from the options given below:

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The order Carnivora includes animal families like Felidae and Canidae. Reason (R): Order being a higher category is assembled on the basis of a higher number of similar characters than those shared within a family. In the light of the above statements, choose the correct answer from the options given below:

As one moves from Species up to Kingdom in the taxonomic hierarchy, which of the following trends correctly describes the changes in the number of common characters and the complexity of determining relationships among taxa?
Read answer →Biology · The Living World
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): As we go higher from species to kingdom in the taxonomic hierarchy, the difficulty of determining the relationship to other taxa at the same level increases. Reason (R): At higher taxonomic categories, the number of common characteristics shared by the members within the taxon decreases. In the light of the above statements, choose the correct answer from the options given below:

Consider the following statements regarding taxonomic ranks: (A) Genus comprises a group of related species which has more characters in common in comparison to species of other genera. (B) Families are characterized on the basis of both vegetative and reproductive features of plant species. (C) Order being a higher category is the assemblage of families which exhibit a higher number of similar characters compared to genus. (D) Solanum, Petunia, and Datura are placed in the family Solanaceae. Which of the above statements are correct?

The plant families Convolvulaceae and Solanaceae are grouped together under the Order Polymoniales. This taxonomic grouping is primarily based on which set of characters?
Read answer →Biology · The Living World
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Taxonomic categories and hierarchy are merely morphological aggregates of organisms with no distinct biological reality. Reason (R): Category denotes rank, and each rank or taxon in fact represents a unit of classification which is a distinct biological entity. In the light of the above statements, choose the correct answer from the options given below:

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Scientific names ensure that each organism has only one name all over the world and is not used for any other known organism. Reason (R): Scientific names are based on agreed principles and criteria provided in ICBN for plants and ICZN for animals. In the light of the above statements, choose the correct answer from the options given below:

(B) Both words in a biological name, when handwritten, are separately underlined to indicate their Latin origin. (C) The first word denoting the genus starts with a small letter, while the specific epithet starts with a capital letter. (D) Name of the author appears after the specific epithet in an abbreviated form and is printed in italics. Which of the above statements are correct?
