classificationState the merits of whittakers method of classification
Answers
The five-kingdom classification has certain drawbacks also, particularly with reference to the lower forms of life.
· The kingdoms Monera and Protista include diverse, heterogeneous forms of life. In both the kingdoms there are photosynthetic (autotrophic) as well as non-photosynthetic (heterotrophic) organisms. Both the kingdoms include organisms which have cells with cell wall as well as without cell wall.
· None of the three higher kingdoms include a single ancestor of all its forms.
· Multicellular lines have originated from protistans several times.
· Unicellular green algae like Volvox and Chlamydomonas have not been included under Protista because of their resemblance to other green algae.
· Slime moulds differ totally from other members of Protista in their general organization.
· Viruses have not been given proper place in this system of classification
