Weekly Quiz Competition

Question 1
1 / -0

As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics

A
Will decrease

B
Will increase

C
Remain same

D
May increase or decrease

Solution

Number of common characters is maximum among members of a particular species. On the other hand, number of common characters is minimum among members of a particular kingdom.
Question 2
1 / -0

Which of the following ‘suffixes’ used for units of classification in plants indicates a taxonomic category of ‘family’.

A
– Ales

B
– Onae

C
– Aceae

D
– Ae

Solution

You can consider the names of families, e.g. Solanaceae, fabaceae, etc.
Question 3
1 / -0

The term ‘systematics’ refers to:

A
Identification and study of organ systems of plants and animals

B
Identification and preservation of plants and animals

C
Diversity of kinds of organisms and their relationship

D
Study of habitats of organisms and their classification

Solution

In fact, the need for a proper classification system was felt because of huge diversity of organisms. Based on certain relationships, organisms were classified into different group and sub-groups.
Question 4
1 / -0

Genus represents

A
An individual plant or animal

B
A collection of plants or animals

C
A group of closely related species of plants or animals

D
None of these

Solution

Taxon genus is just above the taxon species.
Question 5
1 / -0

The taxonomic unit ‘Phylum’ in the classification of animals is equivalent to which hierarchical level in classification of plants

A
Class

B
Order

C
Division

D
Family

Solution

In animal kingdom, phylum comes just after the kingdom. Similarly, in the plant kingdom, division comes just after the kingdom.
Question 6
1 / -0

Botanical gardens and zoological parks have

A
Collection of endemic living species only

B
Collection of exotic living species only

C
Collection of endemic and exotic living species

D
Collection of only local plants and animals

Solution

To understand this, you can visit the zoo at Delhi or Kolkata. You can also search in Google image and you will find giraffes; along with tigers and lions. Tigers and lions are endemic species while giraffe is an exotic species.
Question 7
1 / -0

Taxonomic key is one of the taxonomic tools in the identification and classification of plants and animals. It is used in the preparation of

A
Monographs

B
Flora

C
Both a & b

D
None of these
Question 8
1 / -0

All living organisms are linked to one another because

A
They have common genetic material of the same type

B
They share common genetic material but to varying degrees

C
All have common cellular organization

D
All of above

Solution

In fact, the whole theory of evolution is based on similarity of genetic materials which indicates towards common ancestry for living organisms. Variations in similarity of genetic material give biodiversity which we see all around us.
Question 9
1 / -0

Which of the following is a defining characteristic of living organisms?

A
Growth

B
Ability to make sound

C
Reproduction

D
Response to external stimuli

Solution

Rest of the characters may not be apparent at every instance of time. But response to external stimuli can always be confirmed as and when required. So, this is considered as a defining characteristic of living organisms.

Question 10

1 / -0

Match the following and choose the correct option:

Column I	Column II
(a) Family	i. tuberosum
(b) Kingdom	ii. Polymoniales
(c) Order	iii. Solanum
(d) Species	iv. Plantae
(e) Genus	v. Solanacea

(a)-v, (b)-iv, (c)-ii, (d)-i, (e)-iii

(a)-iv, (b)-iii, (c)-v, (d)-ii, (e)-i

(a)-iv, (b)-iii, (c)-v, (d)-i, (e)-ii

(a)-iv, (b)-iii, (c)-ii, (d)-v, (e)-i

Solution

The order of taxa is as follows: Kingdom Order Family Genus Species

Classification of potato:

Kingdom: Plantae

Order: Solanales
