Explanation

Classification of higher plants  is based on  floral characters, because floral characters are more stable and permanent.

Study of endemism is important to a plant taxonomist because.

  1. Of wide distribution of endemics

  2. Endemics have been subjected to major climatic revolutions

  3. Taxonomist is equally concerned with the history of floras

  4. Endemics have not been physiographically isolated
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Endemism refers to species restricted to a particular geographic region. Studying endemism helps plant taxonomists understand the historical development, origin, and evolution of floras in specific areas.

Consider the following statements with reference to serotaxonomy.
a. The antigen components of plants represent characteristics of taxonomic importance.
b. Both structural and reserve proteins can be used for the classification of plants.
c. Proteins of the same group from different organs are always comparable.
Which of these statements are correct?

  1. $1, 2$ and $3$
  2. $1$ and $2$
  3. $2$ and $3$
  4. $1$ and $3$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Serotaxonomy uses immunological properties of proteins to classify plants. All three statements regarding antigen components, protein types, and comparability are foundational to this approach.

Which nomeclature system is employed for naming plants :

  1. Vernacular

  2. Binomial

  3. Monomial

  4. Polynomial
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Binomial nomenclature is a scientific system of nomenclature for all organisms, including plants. It assigns two names, generic name and specific epithet.
Example, Hibiscus rosa-chinensis, Mangifera indica etc

In Mangifera indica, the word Mangifera is a 

  1. Genus

  2. Species

  3. Variety

  4. Order
Reveal answer Fill a bubble to check yourself
A Correct answer
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'.

The complete name of a plant in binomial nomenclature has?

  1. Three parts(words)

  2. Two parts(words)

  3. Five parts(words)

  4. One part(word)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Binomial nomenclature, established by Linnaeus, dictates that every species name consists of exactly two parts or words. The first word represents the genus and the second represents the specific epithet.

Find out incorrect statements.

  1. Scientific names of plants can be written in any language

  2. There is only one scientific name for a particular plants

  3. All letters of genus name are written in capital

  4. Out of seven taxomic category, two are used to denote scientific name generally
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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.

A scientific name contains information about its

  1. Family and species

  2. Genus and species

  3. Phylum and order

  4. Class and family
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Binomial nomenclature means indication of the name of an organism's 

  1. Order and family

  2. Family and genus

  3. Genus and species

  4. Species and variety
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • 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'.

A Correct answer
Explanation

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.

In which book 'binomial nomenclature' has been used for the first time?

  1. Histoire naturelle

  2. Systema naturae

  3. Historia naturalis

  4. Historia plantarum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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'.

Linnaeus published his concept of binomial nomenclature first in 

  1. Systema Naturae

  2. Species Plantarum

  3. Genera Plantarum

  4. Philosophia Botanica
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

So, the correct option is 'Philosophia Botanica'.
