Explain merits demerits of Whittaexplain merits and demerits of whittaker's classification
Answers
Answer:
The advantages of Whittaker's Five Kingdom Classification are as follows:
-- Prokaryotes differ from all other living organisms in their cell structure and cell multiplication; physiological and biochemical processes.
-- Prokaryotes have been placed separately Kingdom Monera whereas Unicellular and multi- cellular organisms are kept separate.
-- Fungi are also placed in a separate kingdom as their mode of nutrition differs from all other plants.
-- Autotrophs and heterotrophs are also kept separately based on their mode of nutrition
-- Five kingdom classification is more natural than two kingdom classification and is based on bio composition and mode of nutrition.
The disadvantages of Whittaker's Five Kingdom Classification are as follows:
-- Though Unicellular algae are kept in kingdom Protista, but algae- like multicelluar organisms are in kingdom Plantae. So, thumb rule is that similar organisms must be put together.
-- There is diversity in kingdom Protista and dissimilar organisms should not be placed together.
-- All organisms other than Moneran shows their polyphyletic origin which is a limitation of five kingdom classification.
-- Viruses have no separate space for them.
