  1. he was not a naturalist

  3. his classification was based on evolutionary relationships

  4. he took into account the physiological relationships along with morphological observations

Correct Option: B

Multicellular eukaryotic organism with holophytic mode of nutrition belong to how many kingdoms in Whittaker system?

biology why classification? modern classification system traditional method of animal classification salient features of five kingdoms classification hierarchy hierarchy of classification

  1. One

  2. Two

  3. Three

  4. Five

Show answer
Correct Option: A
Explanation:

In Whittaker's five kingdom system of classification, only kingdom Plantae have organisms with a multicellular eukaryotic organism with holophytic nutrition. The organisms which are able to synthesize food by photosynthesis are said to have holophytic nutrition. 


So, the correct option is ' one'.

Which kingdom of Whittaker are not well defined?

  1. Monera

  2. Protisa

  3. Fungi

  4. Animalia

Show answer
Correct Option: A
Explanation:

Monera is the most primitive kingdom mentioned by R.H.Whittaker. It is not well defined among all five kingdoms- Monera, Protista, Fungi, Plants, and Animalia.


So, the correct answer is 'Monera'.

Whittaker is famous for

  1. Two kingdom classification

  2. Four kingdom classification.

  3. Five kingdom classification.

  4. Distinguishing in bacteria and blue green algae.

Show answer
Correct Option: C
Explanation:

The two kingdom classification system was given by Carlous Linnaeus in 1758, who classified living things into two kingdoms: Animal Kingdom (mobile and heterotrophic) and Plant Kingdom (fixed, stationary in the soil, autotrophic). These were then divided into classes and the classes into phyla for animals and divisions for plants. R.H Whittaker proposed the five kingdom classification in 1969, in which all living organisms are divided into five kingdoms based on their complexity of cell structure, complexity of organism’s body and mode of nutrition. The five kingdoms are Monera (prokaryotic BGA and bacteria), Protista (Eukaryotic unicellular organisms; algae and protozoa), Fungi, Plantae and Animalia. The four kingdom classification concept was given by Haeckel who divided living organisms into four kingdoms namely Monera, Protista, Metaphyta and Animalia. BGA and bacteria differ in their kind or reserve food, mode of nutrition, movement and type of photosynthetic pigments. Thus, the correct answer is option C.

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.

  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' .
