A Correct answer
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'.

C Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

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
Reveal answer Fill a bubble to check yourself
D Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Kingdom Protista (often including bacteria in older classifications) has boundaries that are not well defined because it contains diverse organisms that do not fit neatly into other kingdoms.

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

Which one of the following does not find a heterotrophs place in five kingdom system of classification?

  1. Bacteria

  2. Lichens

  3. Cyanobacteria

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

Viruses are considered to be acellular as they do not have a defined cell wall, cell membrane, nucleus or nucleoid, cytoplasm and cellular organelles. For this reason, they cannot perform their metabolic activities on their own and are obligately dependent on the host cell machinery. Therefore, they do not find a place in the five-kingdom classification system. 

A. Bacteria are classified under Kingdom Monera as they have a prokaryotic cell.
B. Lichens are grouped under Kingdom Fungi.
C. Cyanobacteria are photosynthetic prokaryotes grouped under Kingdom Monera.
D. No kingdom is ascribed to the viruses.
Hence, the correct answer is 'Viruses'

Multiple choice biology systematics of living world modern classification system traditional method of animal classification salient features of five kingdoms

Living things are divided into .......... kingdoms.

  1. 4

  2. 3

  3. 5

  4. 2
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Very early on, scientists began grouping the living organisms under different categories. Some biologists classified organisms into plants and animals. Ernst Haeckel, Robert Whittaker, and Carl Woese are some biologists who attempted a broader system of classification. Amongst these, the Five Kingdom Classification proposed by Robert Whittaker stood out and is widely used. It consists of  Monera, Protista, Fungi, Plantae and Animalia
So, the correct answer is '5'
