  1. Phylum

  2. Class

  3. Kingdom

  4. Species

Show answer
Correct Option: C
Explanation:

  • According to the taxonomical hierarchy, the kingdom is the highest category in biological classification. It is a group of closely related organisms. 
  • Kingdom → Phylum → Class → Order → Family → Genus → Species.
  • Example: All plants have common features of the autotrophic mode of nutrition and the presence of a cell wall made up of cellulose. Hence, they belong to the kingdom Plantae.
So, the correct option is 'Kingdom'.

Show answer
Correct Option: A
Explanation:

In 1860s, the German investigator Ernst Haeckel proposed a three-kingdom system of classification. Haeckel's three kingdoms were Animalia, Plantae, and Protista.

Show answer
Correct Option: B
Explanation:

In Vedic times, the ;living organisms were divided into the following:

1. Born from the womb (Jivagi.)
2. Born from egg (Andaja.)

  1. Haeckel

  2. Pasteur

  3. Lister

  4. Koch

Show answer
Correct Option: A
Explanation:

In the year 1866, Ernst Haeckel proposed the three kingdom classification. The three kingdoms are protista, plantae and animalia. The unicellular prokaryotic organisms were placed in the group of monera. This group includes the organisms which have chloroplast and resemble plants as well as the organisms which resemble animals. The group of protists are divided into two groups as plant-like protists and animal-like protists. 

Thus, the correct answer is option A.

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'.

  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.
