State the merits of Whittaker's method of classification |
|
Answer» 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 Posted 21st July 2011 by NATURAL SCIENTIST |
