Weekly Quiz Competition

Question 1

1 / -0

Match the following books in column A with their authors in column B.

Column A	Column B
(A) Genera Plantarum (3 volumes)	(1) Aristotle
(B) Species Plantarum	(2) Linnaeus
(C) Historia Generalis Plantarum	(3) Bentham and Hooker
(D) Scala Naturae	(4) Plato
	(5) John Ray

A- 4, B- 2, C- 5, D- 3

A- 4, B- 2, C- 1, D- 3

A- 4, B- 2, C- 3, D- 1

A- 3, B- 2, C- 5, D- 1

Solution

Linnaeus established the system of binomial nomenclature in the 1753 edition of Species Plantarum, which is now taken as the starting point for all botanical nomenclature.

Genera Plantarum was an integral part of biological nomenclature. It was established by the Bentham and Hooker

John Ray an English naturalist published important works on botany, zoology, and natural theology. His classification of plants in his Historia Plantarum was an important step towards modern taxonomy.

Scala naturae is the great chain of being. It is is a concept derived from Plato, Aristotle, Plotinus, and Proclus written by Aristotle.

Thus, the correct answer is 'A- 3, B- 2, C- 5, D- 1'.

Question 2
1 / -0

A group of plants with similar traits of any rank is

A
Species

B
Genus

C
Order

D
Taxon

Solution

Taxon is described as a group of organisms that comes under particular classification category. The organisms which are included in one taxon are characterised by similar characteristics or traits. When the group of plants or animals having same characters are placed in the same group, it is called a taxon.
Thus, the correct answer is option D.
Question 3
1 / -0

Who proposed the 'Binomial Nomenclature System'?

A
Whittaker

B
Mendel

C
Carl Linnaeus

D
Tippo

Solution

The binomial system of nomenclature was introduced by Carolus Linnaeus. In this system, he gave scientific names to plants and organisms in which the first part is 'genus' and the second part is 'species'.
Question 4
1 / -0

Identify the correct sequence of taxa in Linnaean hierarchy.

A
Species, genus, family, order, class

B
Class, family, species, genus, order

C
Phylum, class, family, species, order

D
Species, genus, phylum, family, class

Solution

The taxa are the hierarchical ranks which are used for the classification of the organisms. In biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. The correct sequence of groups from most to least inclusive is Kingdom- Phylum- Class- Order- Family- Genus-Species.
Thus, the correct answer is option A.
Question 5
1 / -0

Identify from the following, the only taxonomic category that has a real existence.

A
Genus

B
Species

C
Phylum

D
Kingdom

Solution

A.Correct option B
B. Explanation for correct option:
Species is one of the basics of biological classification and a taxonomic rank. A species is defined as a group of organisms sharing similar characteristics, capable of interbreeding and producing fertile offspring. Thus, they are believed to have an independent existence.
Question 6
1 / -0

Binomial nomenclature means

A
Indication of the name by its order and family

B
Indication of the name by its family and genus

C
Indication of the name by its species and variety

D
Indication of the name by its genus and species

Solution

Correct option: D
Explanation:

Binomial nomenclature is the system of nomenclature in which two terms are used to denote a living organism.
The first one indicates the genus and the second one indicates the species. Both words use Latin grammatical forms.
For example, humans belong to the genus Homo and within this genus to the species Homo sapiens.
Question 7
1 / -0

Name the taxonomic term given to an organism which falls in the same class but not in the same family.

A
Family

B
Genus

C
Species

D
Order

Solution

Species is the lowest taxonomic category which is used for the classification of the living organisms. Genus is next higher category above the level of species. It is a group of species which are related to each other and have fewer characters in common. The family represents groups of related genera. The class represents organisms of related orders which constitutes of the organisms which belong to the same class. These organisms are divided into families and so the organisms from the same order cannot belong to the same family.
Thus, the correct answer is option D.
Question 8
1 / -0

New systematics devoloped by sir Julian Huxley is also called as

A
Phonetics

B
Cladistics

C
Biosystematics

D
Numerical taxonomy

E
Chemotaxonomy

Solution

The term Biosystematics was introduced in 1940 by Julian Huxley. In this system, he considered that species is the product of evolution. This system uses all known characteristics of an organism and evidences from different fields to classify organisms.
Thus, the correct answer is option C.
Question 9
1 / -0

The smallest taxon is called

A
Class

B
Order

C
Genus

D
Species

Solution

The Linnaean system of classification consists of a hierarchy of graded taxonomic (named) ranks that are called as taxa. Species is the smallest and basic or fundamental unit of classification, which comprises of organisms sharing similar characteristics and capable of exchanging genes or interbreeding.
So, the correct answer is option D.
Question 10
1 / -0

The suffix 'idae' refers to

A
Family

B
Genus

C
Order

D
Division

Solution

The suffix 'idae' refers to the family. The taxon which is above the genus level is given a name with standard termination. The termination used to describe their name may depend on the kingdom, phylum and class. For example family Felidae which is a lineage of carnivorous animals. e.g cat
