1
EasyMCQ
Who introduced the system of scientific nomenclature of organisms?
A
Carolus Linnaeus
B
Robert Whittaker
C
Robert Hooke
D
Ernst Haeckel

Solution

(A) Carolus Linnaeus introduced the system of scientific nomenclature,specifically known as binomial nomenclature.
This system provides a unique two-part name to every organism,consisting of a genus name and a species name.

EasyMCQ
The book $Systema \text{ } Naturae$ was written by:
A
Linnaeus
B
Haeckel
C
Whittaker
D
Robert Brown

Solution

(A) The book $Systema \text{ } Naturae$ is a seminal work in the history of biological classification. It was written by Carolus Linnaeus, who is known as the father of modern taxonomy. In this book, he introduced the system of binomial nomenclature for naming organisms.

MediumMCQ
Karl Von Linne was involved with which branch of science?
A
Morphology
B
Taxonomy
C
Physiology
D
Medicine

Solution

(B) Karl Von Linne,also known as Carolus Linnaeus,is widely recognized as the 'Father of Taxonomy'.
He developed the system of binomial nomenclature,which is the formal system of naming organisms that is still used in biology today.
Therefore,he was primarily involved with the branch of science known as Taxonomy.
4
EasyMCQ
Homo sapiens is the scientific name of human beings. What do these two terms imply?
A
Homo is the species and sapiens is the genus.
B
Homo is the genus and sapiens is the species.
C
Both are genus names.
D
Both are species names.

Solution

(B) In binomial nomenclature,the first word represents the genus and the second word represents the species.
Therefore,in the scientific name $Homo$ $sapiens$,$Homo$ is the generic name (genus) and $sapiens$ is the specific epithet (species).
5
Easy
What is binomial nomenclature? List two advantages of naming organisms.

Solution

(N/A) Binomial nomenclature is a formal system of naming living organisms by giving them a two-part name consisting of a generic name (genus) and a specific epithet (species).
Advantages:
$(i)$ It provides a standardized and unique name for each organism,which helps in the systematic study of the wide range of living organisms across the globe.
$(ii)$ It helps in maintaining an accurate record of biodiversity,which is essential for the identification and classification of organisms.
6
Medium
Mention the problem which is associated with using local names of organisms. How was this resolved? Name the scientist who introduced the above solution.

Solution

(N/A) The problem with using local names is that they vary from region to region and language to language,making it difficult for people to know if they are referring to the same organism.
$(b)$ This was resolved by adopting a universal system of naming known as $Binomial$ $nomenclature$,where each organism is given a unique scientific name consisting of two parts: the genus and the species.
$(c)$ The scientist who introduced this system is $Carolus$ $Linnaeus$.
7
Medium
$(a)$ What is the significance of binomial nomenclature?
$(b)$ Who introduced the system of scientific naming?
$(c)$ Write any two conventions followed while writing the scientific names.

Solution

(N/A) Binomial nomenclature is a system of providing a distinct scientific name to organisms,consisting of two components: the first name represents the genus and the second name represents the species. This ensures that an organism has a unique name recognized globally,avoiding confusion caused by local or common names.
$(b)$ The system of binomial nomenclature was introduced by Carolus Linnaeus.
$(c)$ Two conventions followed while writing scientific names are:
$(i)$ The genus name begins with a capital letter,while the species name begins with a small letter.
$(ii)$ When printed,the scientific name is written in italics; when handwritten,both the genus and species names are underlined separately.
8
Medium
Explain the following terms:
$(a)$ Phanerogams
$(b)$ Symbiosis
$(c)$ Binomial Nomenclature

Solution

(N/A) Phanerogams: These are plants with well-differentiated reproductive tissues that ultimately produce seeds. They are also known as seed-bearing plants.
$(b)$ Symbiosis: It is a permanent,mutually dependent relationship between two organisms in which both partners benefit. For example,the association between certain fungal species and blue-green algae (or cyanobacteria) forms lichens.
$(c)$ Binomial Nomenclature: This is a system of naming organisms using two words: the first word represents the generic name (genus) and the second word represents the specific epithet (species).

EasyMCQ
The book 'Systema Naturae' was written by
A
Haeckel
B
Whittaker
C
Robert Brown
D
Linnaeus

Solution

(D) The book 'Systema Naturae' is one of the most significant works in the history of taxonomy.
It was written by Carolus Linnaeus,who is known as the 'Father of Taxonomy'.
In this book,he introduced the system of binomial nomenclature for naming organisms.
Therefore,the correct answer is $D$.

EasyMCQ
The system of scientific naming was introduced by
A
Ernst Haeckel
B
Robert Whittaker
C
Carolus Linnaeus
D
Carl Woese

Solution

(C) The system of scientific naming,known as Binomial Nomenclature,was introduced by $Carolus \ Linnaeus$.
In this system,each organism is given a scientific name consisting of two parts: the genus and the species.
This method provides a standardized way to name organisms globally,avoiding confusion caused by local common names.
