Questions Related to hierarchy of classification

According to Whittaker, kingdom Monera includes

  1. Unicellular eukaryotes

  2. Prokaryotes

  3. Slime molds and protozoa

  4. Multicellular and eukaryotes

Show answer
Correct Option: B
Explanation:

The five kingdom classification was proposed by R. H. Whittaker in the year 1969. The kingdom Monera is comprised of unicellular prokaryotic organisms. This group contains the bacteria and the cyanobacteria species. The other four kingdoms, protista, fungi, plantae and animalia are composed of all the eukaryotic organisms. 

Thus, the correct answer is option B. 

Five kingdom scheme to classify living beings has been proposed by

  1. J. B. S Haldane

  2. G. G. Simpson

  3. E. Mayr

  4. R. H. Whittaker

Show answer
Correct Option: D
Explanation:

R.H.Whittaker was an American plant ecologist who proposed five kingdom scheme. J.B.S.Haldane was a British Indian scientist renowned for his innovative contributions in statistics and biostatics. George Gaylord Simpson was a palaeontologist. Ernst Mayr was a biologist.

The correct answer is D. 

Which of the following is not one of the five kingdoms of R. H. Whittaker's classification system?

  1. Animalia

  2. Monera

  3. Protista

  4. Chordate

Show answer
Correct Option: D
Explanation:

Robert H. Whittaker in 1969, proposed five kingdom system of classification of organisms. The following three criteria were used for classification:

1) Complexity of cell structure
2) Complexity of the organism's body
3) Mode of nutrition.
Five kingdoms of Whittaker's classification include Monera, Protista, Fungi, Plantae, Animalia. Hence option D is the correct answer. 

Kingdom in which boundaries are not well defined includes _____________.

  1. Sole organisms as bacteria

  2. Organisms live as predators or parasites also

  3. Organism primarily terrestrial

  4. Achlorophyllous, spore producing organisms with loose tissue level today organisation

Show answer
Correct Option: A

Five kingdom system of classification suggested by R.H. Whittaker is not based on.

  1. Mode of reproduction

  2. Mode of nutrition

  3. Complexity of body organisation

  4. Presence or absence of well defined nucleus

Show answer
Correct Option: A
Explanation:
  • R. H. Whittaker's five-kingdom classification is mainly based on Cell structure, Thallus organization,  Mode of Nutrition, Mode of reproduction and Phylogenetic relationship.

So the correct option is 'Presence or absence of a well-defined nucleus.'

Read the following statements and find out the correct statement:-
(a) Human being can move limbs, jaws,eyelids and earpinna etc.
(b) Streaming of protoplasm in unicellular organism like amoeba is a simple form of movement
(c) Movement of significant feature of living beings.
(d) movement of cilia, flagella are shown by many organism.

  1. a,b,c

  2. b,c,d

  3. c,d,a

  4. d,a,b

Show answer
Correct Option: D
Explanation:

Human beings can move their limbs, jaws, eyelids, and ear pinna etc. These movements are referred to them by the presence of voluntary muscles and a framework of the body that allows Movement in such possible ways.

Streaming of Protoplasm in a unicellular organism like Amoeba is a simple form of movement as it allows them to move in a media.
Movement of cilia, flagella are shown by many organisms ranging from algae, protozoa to certain animals in the animal kingdom.
However, the movement is not a significant defining feature of living beings, for example, the sponges are living beings however majority of them are immovable plants also show similar characteristics.
So the correct answer is 'd, a, b' .
