1. In taxonomy, a group of individual organisms with fundamental similarities is called what?
Correct Answer: B
A species is the basic unit of biological classification. It consists of organisms that share fundamental similarities in structure and characteristics. Members of a species resemble each other closely and are distinct from organisms of other species. Species represents the lowest level in the taxonomic hierarchy. In biological studies, species is considered the primary unit for identification and classification of living organisms.
2. One species can be distinguished from closely related species based on what differences?
Correct Answer: C
Species are distinguished from one another based mainly on morphological differences. Morphology refers to the form and structural features of organisms. Differences in shape, size, body structure and other visible characters help scientists identify and separate closely related species. Even species belonging to the same genus may look similar but show distinct structural variations that allow proper identification.
3. In the name Mangifera indica, the word 'indica' represents what?
Correct Answer: C
In binomial nomenclature, the second word of a scientific name is called the specific epithet. It identifies the particular species within a genus. In the name Mangifera indica, 'Mangifera' is the genus and 'indica' specifies the exact species. The specific epithet distinguishes one species from other species belonging to the same genus.
4. In the name Panthera leo, the word 'Panthera' represents which taxonomic rank?
Correct Answer: B
In scientific naming, the first word always represents the genus. A genus is a taxonomic category higher than species and groups together closely related species that share important morphological similarities. In Panthera leo, 'Panthera' indicates the genus to which lion belongs.
5. The first word in a scientific name generally represents which category?
Correct Answer: B
Scientific names follow binomial nomenclature, where the first word represents the genus. The genus groups together related species with similar structural features. It is written with an initial capital letter and forms the first part of every biological name.
6. A genus may contain how many specific epithets representing different organisms?
Correct Answer: C
A genus can include one or more species. Each species within a genus is represented by a different specific epithet. Although species within the same genus share morphological similarities, they are distinct organisms with their own unique characteristics.
7. Different species within the same genus share what type of similarities?
Correct Answer: B
Species placed within the same genus share morphological similarities. This means they have similar structural features and body organization. These similarities indicate close evolutionary relationships and justify grouping them under the same genus.
8. The genus Panthera includes which other specific epithet besides leo?
Correct Answer: C
Panthera is a genus that includes multiple species. Besides Panthera leo (lion), it also includes Panthera tigris (tiger). Both species belong to the same genus because they share morphological similarities but differ enough to be classified as separate species.
9. Human beings belong to which species according to scientific classification?
Correct Answer: B
In the scientific name Homo sapiens, 'sapiens' represents the species. Species identifies the specific organism within a genus. Humans are classified under the genus Homo and the species sapiens, making their scientific name Homo sapiens.
10. Human beings are grouped under which genus in biological classification?
Correct Answer: C
Humans are classified under the genus Homo. A genus groups together species that share close similarities in structure and evolutionary relationships. Homo is the genus that includes modern humans.
11. What is the correct scientific name of human beings?
Correct Answer: B
The correct scientific name of human beings is Homo sapiens. In this binomial name, Homo represents the genus and sapiens represents the species. Scientific names are written in two parts to clearly identify organisms in biological classification.
12. A genus is defined as a group of organisms consisting of what type of species?
Correct Answer: B
A genus is a taxonomic category that groups together closely related species. Species placed within the same genus share more structural and morphological similarities with each other than with species of other genera. The genus represents a higher rank than species and acts as a broader grouping category in classification. It helps organize related species under a common name.
13. Species placed under the same genus share what level of similarity?
Correct Answer: B
Species belonging to the same genus share more characters in common compared to species placed in different genera. These similarities are mainly structural and morphological. Because of these shared features, such species are grouped together under a common genus name in biological classification.
14. Potato and brinjal belong to which common genus?
Correct Answer: C
Potato and brinjal are two different species but both are placed under the genus Solanum. Although they are separate species, they share important similarities that justify grouping them under the same genus in plant classification.
15. Lion, tiger and leopard belong to which genus?
Correct Answer: B
Lion (Panthera leo), tiger (Panthera tigris) and leopard (Panthera pardus) are different species but share many common features. Due to these similarities, they are grouped under the genus Panthera.
16. Which genus includes cats according to biological classification?
Correct Answer: B
The genus Felis includes cats. Although Panthera and Felis are related genera within the same family, they differ from each other based on specific morphological and structural features.
17. In biological classification, a family consists of what grouping?
Correct Answer: B
A family is a higher taxonomic category that includes a group of related genera. Compared to genus and species, similarities at the family level are fewer, but organisms still share important characteristics that justify grouping them together.
18. Families in plants are characterised mainly based on which features?
Correct Answer: C
Plant families are characterized based on vegetative features such as leaves and stems, and reproductive features such as flowers and fruits. These structural features help scientists group related genera under a common family.
19. Solanum, Petunia and Datura belong to which plant family?
Correct Answer: B
The genera Solanum, Petunia and Datura are grouped under the plant family Solanaceae. Although they are different genera, they share similarities in vegetative and reproductive features.
20. Panthera and Felis are grouped together under which animal family?
Correct Answer: C
The genera Panthera and Felis are placed under the family Felidae. Although they represent different genera, they share similarities that justify grouping them within the same animal family.
21. Cat and dog are placed in which respective animal families?
Correct Answer: A
Cat belongs to the family Felidae, while dog belongs to the family Canidae. Although they share some similarities, they differ sufficiently to be placed in separate families in animal classification.
