  1. Quasibinomial system

  2. Semibinomial system

  3. Mononomial system

  4. Uninomial system


Correct Option: D
Explanation:

The system of giving one name to the individual is called uninomial system. This system was introduced with certain advantages for different purposes. The rules given by Linnaeus in the binomial system were considered quite complicated. To simplify the system and overcome these problems, Heywood suggested that two components of the name- generic name and specific epithet may be united together to form a single name.

The binomial system of naming a species was first devised by

  1. Aristotle

  2. Hugo de Vries

  3. Carolus Linnaeus

  4. Bentham and Hooker


Correct Option: C
Explanation:

The binomial system of naming a species was first devised by Swedish botanist and physician Carolus Linnaeus.

In Mangifera indica, the word Mangifera is a 

  1. Genus

  2. Species

  3. Variety

  4. Order


Correct Option: A
Explanation:
According to the binomial system of classification, each name has two components, the generic name and the specific epithet. Linnaeus introduced the binomial system of classification. 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.
So, the correct answer is 'Genus'.

Which of the following combinations form a binomial epithet?

  1. Generic epithet + specific epithet

  2. Specific epithet + author citation

  3. Generic epithet + author citation

  4. Generic epithet + specific epithet + author citation


Correct Option: A
Explanation:
Binomial nomenclature is a system of naming living species in which each species is assigned a specific scientific name. The name consists of two parts:
  • Generic epithet: It shows the genus of the organism
  • Specific epithet: It shows the species of the organism.
So, the correct answer is 'Generic epithet + specific epithet'.

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

  1. Exocoetus - flying frog

  2. Betta - Fighting fish

Taxonomy (biology), a branch of science that encompasses the description, identification, nomenclature, and classification of organisms.

Physiology is the scientific study of normal function in living systems.
Paleontology is the study of fossils.
Mycology is the branch of biology concerned with the study of fungi.
Therefore, the correct answer is option B.

A scientific name contains information about its

  1. Family and species

  2. Genus and species

  3. Phylum and order

  4. Class and family


Correct Option: B
Explanation:
A scientific name contains information about its genus and species.
The scientific name of an organism is used to identify it anywhere in the world. Under binomial system of nomenclature, each organism has scientific name consisting of two parts. First part is genus and second part is the species. For example- the scientific name of mango is Mangifera indica, scientific name of house fly is Musca domestica.

In binomial nomenclature, the first name refers to

  1. Order

  2. Class

  3. Genus

  4. Species


Correct Option: C
Explanation:

In binomial nomenclature, the first name refers to the genus. The second part is a species name.

The first part of the binomial, the genus name, is always written with an initial capital letter. In current usage, the second part is never written with an initial capital.

A binomial scientific name contains 

  1. Names of genera and family

  2. Names of genera and species

  3. Names of species and class

  4. Names of class and kingdom


Correct Option: B
Explanation:

Binomial nomenclature is the formal naming system for living things that all scientists use. It gives every species a two-part scientific name. For example, a ladybug found in the United States goes by the fancy name of Harmonia axyridis. The first part of a scientific name, like Harmonia, is called the genus. A genus is typically the name for a small group of closely related organisms. The second part of a scientific name, axyridis in this example, is the specific epithet. It is used to identify a particular species as separate from others belonging to the same genus. Together, the genus plus the specific epithet is the full scientific name for an organism. 

Therefore, the correct answer is option B.

Naming and classification of organisms is known as

Which of the following biologists is responsible for the binomial system for naming organisms that we use today?

  1. Carolus Linnaeus

  2. Whittaker

  3. Theophrastus

  4. Aristotle


Correct Option: A
Explanation:

Carolus Linnaeus proposed the binomial nomenclature. The purpose of binomial nomenclature was to provide universal identification to the living organism. The system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet is known as binomial nomenclature.

R.H Whittaker gave five kingdom classification which classified the living organism into Monera, Protista, Fungi, Plantae and Animalia.
Theophrastus is known as the father of botany.
Aristotle is known as the father of zoology.
So, the correct answer is option A.

The usage of binomial names, for plant species was accepted by all after the publication of the work by 

  1. Hooker

  2. Linnaeus

  3. Bentham

  4. Darwin


Correct Option: B
Explanation:

Linnaeus is considered father of taxonomy and was first to use the binomial nomenclature for organisms in his book “Species Plantarum, 1753” in which he gave a generic name to each species. The generic names was followed by trivial name that represented the specific epithet and hence, the system of binomial nomenclature; option B is the correct answer. Benthum and Hooker proposed the most elaborate natural classification of seed plants in their three volume book “Genera Plantarum, 1863-83”. This makes options A and C incorrect as their work was published much later than that of Linnaeus. Darwin is best known for his theory of natural selection to explain the process of evolution. Thus, the correct answer is option B. 

According to binomial nomenclature system, scientific name includes two terms. They are

  1. Genus and species

  2. Class and order

  3. Genus and phylum

  4. two names, one denoting the .latinised name of the, place and the other of the person, who determined it


Correct Option: C
Explanation:

  • The local name of thousands and thousands of plants and animals varies from place to place.
  • Hence, there is a need to standardize the naming of a living organism such that a particular organism is known by the same name all over the world.
  • And so Binomial Nomenclature was given.
  • The first name denotes the name of the genus and second denotes the Species name.
Hence, the correct answer is 'One scientific name consisting of a generic and a specific epithet.'.

State whether the following statements are true or false.
In binomial nomenclature, the name of an organism consists of two words in Latin; the first word denotes the specific name and the second the generic name.

  1. True

  2. False


Correct Option: B
Explanation:

  • The local name of thousands and thousands of plants and animals varies from place to place.
  • Hence, there is a need to standardize the naming of a living organism such that a particular organism is known by the same name all over the world.
  • And so Binomial Nomenclature was given.
  • The first name denotes the name of the genus and second denotes the Species name.
Hence, the correct answer is 'False'.

The internationally recognised binomial nomenclature was developed by linnaeus in his book 

  1. Philosophia Botanica

  2. Historia Plantarum

  3. Species Plantarum

  4. None of these


Correct Option: B
Explanation:

  • Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, genus and specific epithet. 
  • The formal introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work Species Plantarum in 1753.
So, the correct option is 'Species Plantarum'.

Binomial system of nomenclature means that every organism has___________

  1. Two names, one scientific and the other popular

  2. One name given by two scientists

  3. One scientific name consisting of a generic and specific name

  4. A number in an international catalogue by which it can be identified


Correct Option: C
Explanation:
 C Linnaeus, the father of taxonomy, introduced the binomial system of nomenclature. He dealt about this in the 10th edition of his book 'Systema Naturae' which was published in 1785.
This is a system of providing organisms with distinct scientific names which consist of two words, the first one indicating a generic name (Genus). The first and second together form a specific name (Species). These two words are in Latin or Latinized if derived from other languages.
Genus is a common noun and starts with a capital letter. It indicates the name of a group. In the specific name, the second word is like an adjective and begins with a small letter excepting the cases when it denotes proper nouns like the name of a person, place or the like. It may then, start with a capital letter.
The names when written should be underlined to indicate their Latin origin. In the printed form, they should be italicized.
The name of the author who has first described the plant in scientific journals may be appended in full or abbreviated form. For example - the botanical name of mango is Mangifera indica Linn. All three comprise binomial nomenclature.
The generic name is one for all species whereas the species name is variable. For example - Ficus bengalensis, Ficus religiosa, Ficus glomerata, which represent banyan, peepul and fig trees respectively. All have one generic name Ficus but their species names are F.bengalensis, F.religiosa, F.glomerata.

Who proposed the 'Binomial Nomenclature System'?

  1. Whittaker

  2. Mendel

  3. Carl Linnaeus

  4. Tippo


Correct Option: C
Explanation:

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'.

A major problem with polynomial names was that they were

  1. Inaccurate

  2. Cumbersome

  3. Not descriptive

  4. In Latin


Correct Option: B
Explanation:

  • The term nomenclature means the scientific naming of organisms according to an established system. In earlier days common vernacular names were used which generally changes with change of language. Later in the haunt of one common internationally accepted name for a species, scientific names (Technical names) have been introduced in the form of polynomial, binomial and trinomial systems of nomenclature.
  • In the early seventeenth century, taxonomists started using a string of descriptive Latin words to designate a species. For example, in the herbal of Clusius (1583) a species of willow is named as Salix pumila angustifolia altera.
  • Polynomial nomenclature was discarded for the two main reasons that it was lengthy and difficult to remember, it often varies from place to place, scholar to scholar based on the characters chosen by them.
So the correct option is 'Cumbersome'.
