Question 1
1 / -0

Give the binomial nomenclature for the given plant species.

A
Solanum tuberosum

B
Allium cepa

C
Aloe vulgaris

D
Azadirachta Indica

Solution

The given plant species is Aloe vera. Its binomial nomenclature is Aloe vulgaris. It is an evergreen perennial. It is used in the treatment of skin diseases like psoriasis and dermatitis.
Thus, the correct answer is 'Aloe vulgaris.
Question 2
1 / -0

Find out the number of biological species from the given:
Monkey, Horse, Donkey, Mule, Blue-green algae

A
$$3$$

B
$$5$$

C
$$4$$

D
$$2$$
Solution
- Species is defined as the group of organisms that are capable of interbreeding and produce fertile offspring.
- Monkey, Horse, Donkey and Blue-green algae all are examples of different species based on this definition.
- Mule is a product of interspecific hybridisation incapable of interbreeding as it is sterile.
- So, the correct option is '4'.
Question 3

In Mangifera indica, the word Mangifera is a

A
Genus

B
Species

C
Variety

D

The first part of the name identifies the genus to which the species belongs, the second part, the specific name or specific epithet which identifies the species within the genus. According to the binomial system of classification in Mangifera indica, the word Mangifera is a genus.

Why hierarchical taxonomic system is used?

A
As each higher taxonomic category contains group categories below it

B
It is helpful to establish classification

C
All taxonomic categories reflect common habitats

D
Taxonomic group show similar characters and have no evolutionary relationship

Solution

A taxon is a taxonomic group that belongs to any rank in a given system of classification. Taxonomic categories are arranged in a proper descending order and this is called a taxonomic hierarchy. The kingdom is the highest rank and species is the lowest rank. Each higher category contains group categories below it, for example, Kingdom consists of various phylum and each phylum consists of various classes.
So, the correct answer is 'As each higher taxonomic category contains group categories below it'.
Question 6
1 / -0

Which of the following is correct match of genetic name with it's common name?

A
Exocoetus - flying frog

B
Betta - Fighting fish

C
Toad - Tree frog

D
Pristis - Electric fish

Solution

A flying frog is an Asian frog which has the ability to achieve gliding flight between trees. Its generic name is Rhacophorus nigropalmatus. The generic name of fighting fish is Betta splendens. It is also called as bettas. Two male fighting fish fight to protect territory. Hence, they are never be placed in the same tank. Tree frog is a frog that spends its most of the live in trees. Its generic name is Hyla arborea. Electric fish is a fish that generates electric field. Its generic name is Electrophorus electricus. It is also called as electric eel.
Thus, the correct answer is 'Betta - Fighting fish.'
Question 7
1 / -0

Which of the following suffix is always correct for taxonomic categories without any exception?

A
"-ia' for class like in class Mammalia

B
"-ca' for genus like in genus Musca

C
"-ceae" for family like is family Poaceae

D
"-oda" for phylum like in phylum Arthopoda
Solution
- Classes may have various suffix such as '-ia' for class Mammalia, '-ea' for class Calcarea etc.
- Genus may have various suffix such as '-ca' for Musca, '-ia' for Scypha etc.
- Family always have the suffix '-ceae' such as Poaceae, Brassicaceae, Ranunculaceae etc.
- Phylum may have various suffix such as '-oda' for Arthropoda, '-era' for Porifera, '-ia' for Cnidaria.
So, the correct answer is '"-ceae" for the family like is family Poaceae'.
Question 8
1 / -0

A taxonomic group of related genera is known as .....

A
Species

B
Order

C
Family

D
Class
Solution
- A taxonomic rank in classification is the relative level of a group of organisms in a taxonomic hierarchy. The order of classification is a kingdom, phylum, class, order, family, genus, and species. A genus is a taxonomic rank.
- It is a group of related species. A family is a higher rank to the genus hence, consists of a group of related genera.
Thus, the correct answer is option C.
Question 9
1 / -0

Which one of the following group of taxa does not represent similar category in hierarchy?

A
Potato and tomato

B
Tiger and leopard

C
Monocots and angiosperms

D
Wheat and mango

Solution

The term taxon (plural - taxa) represents any group or rank in a biological classification into which related organisms are classified. Both potato and tomato may belong to the same family (solanaceae) but in hierarchical classification potato is a plant tuber and tomato is a fruit, hence potato and tomato do not represent similar category in hierarchy
So, the correct answer is 'Potato and tomato'.
