Thus, the traditional plant kingdom comprised bacteria, algae, plants and fungi. Demerits or Limitations: (a) The two kingdom system of classification did not indicate any evolutionary relationship between plants and animals. (b) It grouped together the prokaryotes (bacteria, BGA) with other eukaryotes.
His classification was a two-kingdom system, which had a number of demerits. Subsequently Whittaker proposed a more systematic and elaborates five kingdom system of classification. These systems of classification of living organisms and their merits and demerits are given below. Two Kingdom System.R.H. Whittaker (1969) proposed a Five Kingdom Classification. The kingdoms defined by him were named Monera, Protista, Fungi, Plantae and Animalia. The main criteria for classification used by him include cell structure, thallus organisation, mode of nutrition, reproduction and phylogenetic relationships. Table 2.1 gives a comparative account of different characteristics of the five kingdoms.Various schemes of classification are now available, each having certain merits and demerits. One of the earliest scheme of natural system classification is the two-kingdom classification proposed by Carolus Linnaeus in 1758. Drawbacks of two kingdom classification-There was no distinction between eukaryotes and prokaryotes. For example.
