Multiple Choice Questions (MCQs): The Living World - Question 7

Statement A: Species is the basic unit of classification.
Statement B: Two plants can be said to belong to the same species if they can reproduce freely with each other and form seeds.

A.
Statement B is true but Statement A is false
B.
Both the statements are false
C.
Statement A is true but Statement B is false
D.
Both the statements are true

Detailed Solution: Question 7

Statement A is true because species is indeed the basic unit of classification.
Statement B is false because the correct criterion for two plants to belong to the same species is that they can interbreed and produce fertile offspring, not just form seeds. Sometimes, different species can cross and produce seeds, but those seeds may be sterile or non-viable.

Multiple Choice Questions (MCQs): The Living World - Question 8

Statement A: The process of classification is called taxonomy.
Statement B: Characterisation, identification, classification and nomenclature are basic to taxonomy.

A.
Both the statements are true
B.
Both the statements are false
C.
Statement A is true but Statement B is false
D.
Statement B is true but Statement A is false

Detailed Solution: Question 8

Statement A: False

Taxonomy is not just classification.It is the entire science that deals with characterisation, identification, classification, and nomenclature of organisms.Saying "taxonomy is classification" is an incomplete definition because classification is only one step within taxonomy.

Statement B: True

This correctly lists the four basic components of taxonomy:

Characterisation – study of characters of organisms
Identification – assigning an organism to a known group
Classification – arranging organisms into categories (kingdom, phylum, etc.)
Nomenclature – providing scientific names

Thus, taxonomy is a broader concept, and classification is just one part of it.

Multiple Choice Questions (MCQs): The Living World - Question 9

The action that the environment does on an organism is called ________

A.
Response
B.
Stimulus
C.
Reflex
D.
Reaction

Detailed Solution: Question 9

The term stimulus refers to any change or action from the environment that affects an organism and can cause it to react. For example, touching a hot surface is a stimulus for a person, and the person pulling their hand away is the response. Thus, the action that the environment does on an organism is called a stimulus, while the organism's behavior or movement resulting from it is called the response.

Multiple Choice Questions (MCQs): The Living World - Question 10

Metabolism means ________

A.
division of cells
B.
production of progeny
C.
Expansion of Cell
D.
series of chemical reactions

Detailed Solution: Question 10

Metabolism refers to a series of chemical reactions that occur in a living organism to sustain life.

Multiple Choice Questions (MCQs): The Living World - Question 11

Which taxonomic category is used to group related genera?

A.
Family
B.
Species
C.
Order
D.
Class

Detailed Solution: Question 11

The Family taxonomic category is used to group related genera that share more similarities with each other than with genera in other families. This level of classification reflects broader evolutionary relationships and morphological similarities among organisms. For example, the family Felidae groups together the genera Panthera (lions, tigers) and Felis (domestic cats), which share many characteristics distinct from those in other animal families.

Topic in NCERT: Family

Line in NCERT: "the next category, family, has a group of related genera with still less number of similarities as compared to genus and species."

Multiple Choice Questions (MCQs): The Living World - Question 12

Primate and Carnivora are placed together in the same?

A.
Class
B.
Division
C.
Family
D.
Order

Detailed Solution: Question 12

Primates and carnivores are the two ordered of the same class called Mammalia. Primata and carnivores are placed together as belonging to the same class.

Topic in NCERT: Order

Line in NCERT: "this category includes related orders. for example, order primata comprising monkey, gorilla and gibbon is placed in class mammalia along with order carnivora that includes animals like tiger, cat and dog."

Multiple Choice Questions (MCQs): The Living World - Question 13

The smallest unit of classification is known as:

A.
Species
B.
De condole
C.
Linnaeus
D.
Mayr

Detailed Solution: Question 13

The smallest unit of classification is known as species, which is a group of closely related organisms who can interbreed and produce fertile offspring. The organisms in a species share a genetic heritage.

The correct answer is A.

Topic in NCERT: Species

Line in NCERT: "all organisms, including those in the plant and animal kingdoms have species as the lowest category."

Multiple Choice Questions (MCQs): The Living World - Question 14

What is the difference between the taxonomic categories, division and phylum?

A.
Division is a group of closely related organisms.
B.
Phylum is a group which is a group of orders.
C.
Division is used in the place of phylum category in plants, and phylum is used in animals.
D.
Division is the same as the kingdom and phylum are more exclusive than division.

Detailed Solution: Question 14

Division is used in the place of phylum category in plants and phylum is used in animals.
Phylum is a rank in the classification of organisms, below kingdom and above class.

Topic in NCERT: Phylum

Line in NCERT: Classes comprising animals like fishes, amphibians, reptiles, birds along with mammals constitute the next higher category called Phylum. All these, based on the common features like presence of notochord and dorsal hollow neural system, are included in phylum Chordata. In case of plants, classes with a few similar characters are assigned to a higher category called Division.

Multiple Choice Questions (MCQs): The Living World - Question 15

Which among the following best describes the word “Growth” in living organisms?

A.
Increase in mass either due to accumulation or due to changes that body undergoes internally
B.
Growth is a sufficient characteristic to determine whether an organism is living or non-living
C.
All living organisms grow throughout their life
D.
Increase in mass due to internally cell division and increase in number due to replication are twin characteristic of growth

Detailed Solution: Question 15

Increase in mass due to internal division and increase in number of organisms are twin characteristics of growth.
In non-living organisms increase in mass occurs due to accumulation whereas in living organisms it happens due to the proteins and carbohydrates that we intake.
Living organisms except plants grow until certain period of their life and then stop growing.
Growth is not a sufficient a characteristic to determine if an organism is living.
Sometimes it’s possible that even mountains and sand dunes grow due to an accumulation of sand.

Multiple Choice Questions (MCQs): The Living World - Question 16

What does the specific epithet 'leo' refer to in Panthera leo?

A.
Genus
B.
Family
C.
Species
D.
Order

Detailed Solution: Question 16

In the binomial nomenclature system, the second part of the name, 'leo' in Panthera leo, is the specific epithet and refers to the species. This system, developed by Carl Linnaeus, ensures each species has a unique, universally accepted scientific name comprising a genus name followed by a specific epithet.

Topic in NCERT: Taxonomy and nomenclature

Line in NCERT: "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."

Multiple Choice Questions (MCQs): The Living World - Question 18

The scientific term for biological classification categories is the:

A.
Species
B.
Taxon
C.
Phylum
D.
Domain

Detailed Solution: Question 18

The correct answer is B: Taxon.

- Taxon is the scientific term for biological classification categories.
- It refers to a group of organisms in a classification system.
- Taxonomic ranks include domain, kingdom, phylum, class, order, family, genus, and species.
- Each taxon represents a specific level in the hierarchy of biological classification.
- Taxonomic classification helps scientists organize and understand the diversity of life on Earth.

Topic in NCERT: Taxonomic categories

Line in NCERT: "the scientific term for these categories is taxa."
