Question 141 of 214

📘 CLASS XI

Assertion (A): Taxonomic groups and categories are distinct biological entities.

Reason (R): Taxa are not merely morphological aggregates.

Both statements are correct and complementary, but the reason is not a direct explanation.

Question 142 of 214

📘 CLASS XI

Assertion (A): The basic requirement for placing an organism in various taxonomic categories is knowledge of its characters.

Reason (R): Knowing an organism's characters helps in identifying similarities and dissimilarities among individuals.

Knowledge of characters enables comparison of similarities and differences essential for classification.

Question 143 of 214

📘 CLASS XI

Assertion (A): All organisms, including plants and animals, have species as the lowest taxonomic category.

Reason (R): Taxonomic studies consider a group of individual organisms with fundamental similarities as a species.

The reason defines species but does not directly explain why it is the lowest taxonomic category.

Question 144 of 214

📘 CLASS XI

Assertion (A): Closely related species are distinguished from one another based primarily on their geographical location.

Reason (R): One should be able to distinguish closely related species based on distinct morphological differences.

Species are primarily distinguished by morphological differences rather than geographical distribution.

Question 145 of 214

📘 CLASS XI

Assertion (A): A single genus can only ever have one specific epithet associated with it.

Reason (R): Each genus may have one or more than one specific epithets representing different organisms with morphological similarities.

A genus may include multiple species, each with a different specific epithet.

Question 146 of 214

📘 CLASS XI

Assertion (A): Potato (Solanum tuberosum) and brinjal (Solanum melongena) belong to the same genus.

Reason (R): Genera are aggregates of closely related species that have more characters in common compared to species of other genera.

Potato and brinjal are different species grouped under the genus Solanum because of their close similarities.

Question 147 of 214

📘 CLASS XI

Assertion (A): The genus Panthera and the genus Felis are completely identical in all morphological features.

Reason (R): The genus Panthera includes lion, leopard and tiger, and differs from the genus Felis, which includes cats.

Panthera and Felis are different genera because they differ morphologically.

Question 148 of 214

📘 CLASS XI

Assertion (A): Plant families are characterized solely on the basis of their reproductive (floral) features.

Reason (R): Families are characterized on the basis of both vegetative and reproductive features of plant species.

Plant families are identified using both vegetative and reproductive characteristics.

Question 149 of 214

📘 CLASS XI

Assertion (A): The genera Solanum, Petunia and Datura are placed in different taxonomic families.

Reason (R): All three of these different genera are placed together in the family Solanaceae.

Solanum, Petunia and Datura all belong to the family Solanaceae.

Question 150 of 214

📘 CLASS XI

Assertion (A): Cats and dogs are separated into two different taxonomic families.

Reason (R): Cats belong to the family Felidae, while dogs belong to the family Canidae.

Cats and dogs differ sufficiently to be placed in separate families: Felidae and Canidae.
