What are the contributions of Whittaker in taxonomy?
He was the first to propose the five kingdom taxonomic classification of the world’s biota into the Animalia, Plantae, Fungi, Protista, and Monera in 1969. He also proposed the Whittaker Biome Classification, which categorized biome-types upon two abiotic factors: temperature and precipitation.
When and who modified the five kingdom classification system of Whittaker?
Answer: The five-kingdom classification was proposed by R. H. Whittaker in the year 1969. The kingdom Monera is comprised of unicellular prokaryotic organisms. The other four kingdoms, Protista, Fungi, Plantae, and Animalia are composed of all the eukaryotic organisms.
What is the criteria used by Whittaker for classification?
The criteria used by R. H. Whittaker for the five kingdom classification were cell structure, thallus organisation, mode of nutrition, reproduction and phylogenetic relationships.
What are the five kingdoms of the Whittaker system of classification?
Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia.
What are the modifications proposed by Margulis and Schwartz in the Whittaker scheme of five kingdom system?
The modifications suggested by Margulis and Schwartz and Whittaker’s scheme was that they proposed the five kingdoms of organisms. They classified the world’s ecologic distribution into five separate entities that are known as Plantae, Protista, Animalia, Monera and Fungi. The modification was carried out in 1969.
What changes are proposed by Margulis and Schwartz in the five kingdom system of Whittaker?
As a result, Margulis and Schwartz modified Whittaker’s scheme to eliminate the limitations and to unite related algae into one kingdom. They suggested that multicellular algae should be placed into the Protist kingdom that was renamed to the Protoctist kingdom.
What are the basis of classification for the five kingdom classification proposed by Whittaker how his classification is better from other?
Five kingdom classification is done on the basis of 5 factors- cell structure, body organization, mode of nutrition, mode of reproduction, and phylogenetic relationship. It also puts unicellular and multicellular organisms into different groups.
What are the advantages and disadvantages of two kingdom classification?
Answer: 1) Plants and animals were divided into two kingdoms not abruptly but based upon specific characters. 2) It initiated systematic methods to classify the living organisms. More and more characters were, later, taken into consideration for development of better methods.
Which of the following is the most important character used by Whittaker in five kingdom classification?
Option 1) Mode of Nutrition According to RH Whittaker, the most important criteria for his five kingdom syste. Of classification is Mode of Nutrition.
Which of the following are criteria used by the Whittaker system to classify organisms?
Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia. The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.
What is Whittaker classification?
Who proposed the five kingdom classification in 1983?
Five kingdom of classification was proposed by RH Whittaker in 1969. He divided all living organisms into five kingdoms based on following features: Complexity of cell structures.

What are the five kingdoms of Lynn Margulis?
In Lynn Margulis Her 1982 book Five Kingdoms, written with American biologist Karlene V. Schwartz, articulates a five-kingdom system of classifying life on Earth—animals, plants, bacteria (prokaryotes), fungi, and protoctists. The protist kingdom, which comprises most.

What kind of plants did Robert Whittaker use?
Whittaker’s functional plant kingdom was an admittedly polyphyletic group of land plants, brown algae, and red algae. He justified this grouping on the grounds of both ecological function and cellular structure.
