Artificial system of classification classifies plants on the basis of

  1. One or very few characters

  2. Phylogenetic trends

  3. Many naturally existing characters

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The major advantage of the artificial system of the classification is considering one or few characters of the plants, so the option (A) is the correct answer.
The phylogenetic trends consideration are all comes under the natural classification, so the option (B) is not the correct answer.
The option (C) refers, many naturally existing characters, which is suitable for the natural classification, not for artificial classification, so the option (C) is also not the correct answer.

Reason for diversity in living being is 

  1. Mutation

  2. Long term evolutionary change

  3. Genetic recombination

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mutation is the sudden change in the genetic composition of the living organism which is inherited from one generation to the other. Due to random changes in the genetic pool, it acts as a source of variation.

In order, to adjust the changing conditions with evolution, the organism undergoes changes in the genome which are inherited by generations and act as a source of diversity.
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent. It leads to change in the genetic pool and act as a source of variation.
So, the correct answer is option D.

Arisotle classify plants into

  1. Trees

  2. Shrubs

  3. Trees, shrubs and herbs

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Classification is the arrangement of living organisms into groups on the basis of similarities and dissimilarities between them and placing within taxonomic hierarchy such as kingdom, genus, species etc. Aristotle was the first to give a scientific basis for classification. He classified living organisms into two groups; plants and animals.
He divided plants into trees, shrubs and herbs on the basis of simple morphological characters.
So, the correct answer is 'Trees, shrubs and herbs'.

First great taxonomist was

  1. Linnaeus

  2. Hooker

  3. Aristotle

  4. Engler
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carolus Linnaeus is a known taxonomist who proposed the classification system and the binomial nomenclature. The classification system is known as the artificial system of classification which is based on the floral characters. The structures of carpel and anther were taken into consideration for the classification. The binomial nomenclature was used for the naming of the organisms in which the first epithet describes the genus and the second epithet describes the species. He is regarded as the father of taxonomy. 
Thus, the correct answer is option A.

Who proposed the natural classification of plants?

  1. Carolus Linnaeus

  2. John Hutchinson

  3. Bentham and Hooker

  4. Oswald Tippo
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The natural system of classification was proposed to classify the organism on the basis of similarities which can be easily observed. The classification takes into consideration the number of similar and different characters. The natural system of classification was introduced by Bentham and Hooker for the plants which have seeds. This was explained in the book Genera Plantarum which was published in three volumes and based on the work of these scientists.

Thus, the correct answer is option C.

The branch dealing with classification is

  1. Genetics

  2. Ecology

  3. Taxonomy

  4. Nomenclature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Genetics is the study of genes, its variation and heredity in organisms. Ecology is the study of the relationship of organisms with one another and with the environment. 
The branch of science dealing with classification of organisms is called as taxonomy.  
Nomenclature is a particular system of naming an individual.
Thus, the correct answer is 'Taxonomy'.

  2. Hooker

  3. Linnaeus

  4. Aristotle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Carl Von Linnaeus is known as the "Father of Taxonomy" owing to his immense contribution to the field of identifying, naming and classifying organisms. He popularized the binomial nomenclature system which is quite popular even today. He published a book named Systema Naturae which dealt with the classification of living organisms.
So, the correct answer is 'Linnaeus'

A system of classification in which a large number of traits are considered is:

  1. Artificial system

  2. Practical system

  3. Phylogenetic system

  4. Natural system
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are three systems of classification, namely artificial, natural and phylogenetic. In natural system of classification, a large number of traits are considered. It is based on morphological, anatomical, cytological, physiological and biochemical characteristics of the organisms. The artificial system of classification is based on observable characteristics of the organisms. The phylogenetic system of classification is based on genetic and phylogenetic relationships between organisms.

Thus, the correct answer is option D.

  4. Nomenclature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Classification of living organisms is covered under the branch "Taxonomy". The word taxonomy was coined by a Swiss Botanist, AP De Candolle who also devised a natural system of classification for plants. Nomenclature is the system of naming organisms scientifically following certain rules laid down by ICBN and ICZN.
So, the correct answer is, 'Taxonomy'.
