Nomenclature in classification - class-XI

Allium sativum, commonly known as garlic is a species of plant belonging to family Liliaceae. Garlic is native to Central Asia or Northeast Iran. It is a bulbous plant which grows in wild areas. It is used both as a food flavouring and as traditional medicine. It is widely used around the world for its pungent flavour as a seasoning or condiment. So, the correct answer is 'Allium sativum'.

Crotolaria juncea, commonly known as sunn hemp, Indian hemp is a tropical Asian plant belonging to legume family Fabaceae.. It is generally considered to as originated in Indian. It is now widely grown throughout the tropics and subtropics as a source of green manure, fodder and lignified fibre. It is also used as biofuel. It is an annual plant and it is an important summer cover crop in the United States. Hence, the scientific name of Sunn hemp is Crotalaria juncea. So, the correct answer is 'Crotalaria juncea'.

The uninominal system is the system for naming entities in which the name for each entity consists of only one word. It differs from the binomial system employed at species level where each individual organism has a name with two components i.e. species and genus.

Saccharum officinarum, commonly known as sugarcane is a large, strong, growing species of grass belonging to family Poaceae. It was originated in New Guinea and it is a perennial plant. It is cultivated in tropical and subtropical countries worldwide for the production of sugars and other products. It is used for the production of sugar, ethanol. the byproducts are used for feeding livestock. So, the correct answer is 'Saccharum officinarum'.

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 Swedish botanist and physician Carolus Linnaeus.

• Generic epithet: It shows the genus of the organism
• Specific epithet: It shows the species of the organism.

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.

Carolus Linnaeus introduced the binomial nomenclature system in his seminal work, Systema Naturae, which laid the foundation for modern biological classification.

Scientific names must follow Latinized rules and are not written in 'any' language. The other statements are generally accepted rules of binomial nomenclature, making A the incorrect statement requested.

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum L. The word "potato" may refer either to the plant itself or the edible tuber. Thus, the correct answer is option A.

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

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

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. 

Cardiology is the branch of medicine that deals with diseases and abnormalities of the heart. 

• Binomial Nomenclature is the system of providing organisms with appropriate and distinct names consisting of two words, first generic and second specific
• The generic word is also called genus and acts like a noun and its first letter is written in the capital form
• The specific epithet represents the species. It is like an adjective and its first letter is written in a small form
• So the correct option is 'genus and species'.

According to binomial nomenclature system, every individual is given a scientific name which includes two terms genus and species.
Lion belongs to Genus Panthera and species Leo.

The scientific name comprises of the genetic name followed by the specific name.

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.

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. 

On the basis of hierarchy of characteristics, the last two units of classification are genus and species. The organism belonging to same genus and species are very much similar.

The 10th edition of 'Systema Naturae' was a book written by Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced the binomial nomenclature for animals.
Thus, the answer is option (B) - 'Systema naturae'.

Brassica nigra is the botanical name of black mustard. 

Philosophia Botanica was published by the Swedish naturalist Carl Linnaeus in 1751 who greatly influenced the development of botanical taxonomy and systematics. It is the first textbook of descriptive systematic botany and botanical Latin. It also contains Linnaeus's first published description of his binomial nomenclature.

The binomial nomenclature of the Touch-me-not plant is Mimosa pudica. This plant is known as touch me not plant because the plant shows a type of nastic movement. Whenever the plant is touched, the leaflets get folded. The stimulus is passed from one branch to the entire branch of the plants. The leaves of the complete plant get folded in response to the touch.

• Binomial nomenclature system was proposed by Carl Linnaeus for the scientific naming of all the plants and animals. Linnaeus proposed the scientific name of plants in his book 'Species Plantarum'.
  
• In binomial nomenclature, each scientific name has two components-generic names (genus) and specific name (species) E.g., Mangifera indica Linn. Mangifera is the genus name and indica is the species name.
  

The current system of International code of botanical nomenclature (ICBN) was adapted to assign the scientific name to plants. It was adapted in 1978 after the twelfth International Botanical Congress held in 1975 to follow the rules for naming the plants. The fifth International Botanical Congress was also held in 1930, at Cambridge (England). So, the correct option is C.

An order is the assemblage of families.

Linnaeus started nomenclature of plants in Latin. At the time of Linnaeus’ work, Latin, the language of science, was taught everywhere and was uniquely suitable for this system of naming plants and animals. European scholars throughout the continent spoke Latin as a common language between various European nations. It is also the mother of all European languages.

• The International Code of Zoological Nomenclature(ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of animals.
• Rules for nomenclature according to ICZN are 1)It consists of two parts one is the genus epithet and the other is species epithet 2)The genus name is always written first 3)The genus name must be capitalized 4)The species epithet is never capitalized 5)The entire two-part name must be written in italics
• Hence Homo sapiens is the correct depiction of ICZN because according to ICZN rules it has two parts one is genus epithet(Homo) and species epithet(sapiens), Both the parts are in italics, Genus name starts with a capital letter and species name starts with small later.
• So, the correct answer is 'Homo sapiens'

Binomial Nomenclature is the method of naming a particular organism by a single standard name known all over the world. The first word represents the genus while the second component represents specific epithet. The first word of the generic name starts with a capital letter and specific epithet starts with a small letter.

• Carolus Linnaeus gave a scientific naming system in which an organism is given a universally accepted name consisting of 2 parts/words.
  
• The first part is the generic name and the second part is the (specific) species name.
  

• Binomial system of nomenclature for plants is effective from 6. 7. 1736.
  
• Each name consists of 2 parts, genus and specific epithet.
• The book Systema Naturae introduced the system of binomial nomenclature.

According to the conventions, suffix '-us' is used at the end of the binomial name at the end of specific epithet while writing the name of animals but is avoided while naming the plants.

1. Carl Linnaeus, a Swedish botanist, physician, and zoologist, laid the foundations for the modern biological naming scheme of binomial nomenclature. He is known as the father of modern taxonomy and is also considered one of the fathers of modern ecology.
   2. The theory of biogenesis was proposed by Louis Pasteur. He proposed that all life originated from pre-existing life. i.e., fishes laid eggs giving rise to more fishes.
   3. The first optical microscope was invented by Zacharias Janssen.
   4. William Harvey is associated with the discovery of blood circulation.
   So, the correct option is 'Binomial nomenclature'.

• 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.

• 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.

• 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.
  

• Naja hunnah- king cobra
  
• Naja naja- Indian cobra
• Vipera russeli- Russell's viper
• Bungarus coerulus- Common krait

• Lepus nigricollis is zoological name of north Indian hare.

The binomial name of frog is Rina tigrina. The study of frogs is called batrachology, belonging to class amphibian of Phylum Chordata. The most common species of frog found in India is Rana Tigrina.

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'.

• 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.
