In the taxonomic hierarchy, family is a higher category than genus. A family includes a group of related genera that share certain similarities, although these similarities are fewer compared to those within a genus or species.
2. In plants, families are characterised mainly based on:
Correct Answer: C
In plant taxonomy, families are identified using both vegetative and reproductive characteristics. Vegetative features include parts like roots, stems, and leaves, while reproductive features include flowers, fruits, and seeds. These characteristics help scientists group related genera into families.
3. The genera Solanum, Petunia, and Datura belong to the family:
Correct Answer: B
In plant classification, the genera Solanum, Petunia, and Datura are grouped under the same family Solanaceae because they share several common vegetative and reproductive characteristics.
4. The genera Panthera (lion, tiger, leopard) and Felis (cats) belong to the family:
Correct Answer: B
In animal classification, the genus Panthera, which includes lion, tiger, and leopard, and the genus Felis, which includes cats, are grouped together in the family Felidae. Members of this family share several common characteristics related to body structure and behaviour.
5. Cat and dog belong to which of the following families respectively?
Correct Answer: B
Cats and dogs share some similarities but also have several differences. Because of these differences, they are placed in different families. Cats belong to the family Felidae, while dogs belong to the family Canidae.
6. Higher taxonomic categories like order are generally identified based on:
Correct Answer: B
In taxonomy, lower categories such as species and genus are based on several similar characters. Higher categories like order are identified using aggregates of many characters. These combined features help scientists group related families into an order.
7. In taxonomy, an order is defined as:
Correct Answer: A
Order is a higher taxonomic category that includes a group of related families. The families grouped under an order share some common characteristics, although these similarities are fewer compared to those within a family or genus.
8. In an order, the similar characters are ______ in number as compared to different genera included in a family.
Correct Answer: B
Order is a higher taxonomic category than family. It includes several families that share only a few similar characters. Therefore, the number of similar characters is less when compared to those among genera within a family.
9. Plant families like Convolvulaceae and Solanaceae are included in the order ______ mainly based on floral characters.
Correct Answer: B
In plant taxonomy, the families Convolvulaceae and Solanaceae are placed in the order Polemoniales. This classification is mainly based on similarities in floral characters such as structure and arrangement of flower parts.
10. The animal order Carnivora includes families such as:
Correct Answer: A
In animal classification, the order Carnivora includes families such as Felidae (cats) and Canidae (dogs). Members of this order are mainly meat-eating animals and share several common characteristics.
11. In taxonomy, a class includes:
Correct Answer: D
In the taxonomic hierarchy, class is a higher category that includes several related orders. Organisms placed in the same class share a number of similar characteristics.
12. Monkeys, gorillas and gibbons belong to the order:
Correct Answer: B
Monkeys, gorillas and gibbons are members of the order Primata (Primates). Animals in this order share several characteristics such as well-developed brains, forward-facing eyes, and grasping hands.
13. Animals like tiger, cat and dog belong to the order:
Correct Answer: B
Tiger, cat and dog are grouped under the order Carnivora. Members of this order are generally flesh-eating animals and share common characteristics related to their teeth and feeding habits.
14. Order Primata (monkey, gorilla, gibbon) and order Carnivora (tiger, cat, dog) are placed in the class ______.
Correct Answer: C
Both the orders Primata and Carnivora are included in the class Mammalia. Members of this class share common characteristics such as the presence of mammary glands, body hair, and warm-blooded nature.
15. Class Mammalia includes:
Correct Answer: B
Class Mammalia is a higher taxonomic category that includes several different orders. Examples include Primata (monkeys, gorillas), Carnivora (tigers, cats, dogs), and other orders of mammals. All these organisms share common mammalian characteristics.
