THE KINGDOM PROKARYOTAE

 

It was Haeckel, who first and foremost in the year 1866 vehemently suggested that the microorganisms present in the particular kingdom, Protista, should essentially be composed of both the prokaryotes as well as the eukaryotes. Almost a century later, Murray in 1968 unequivocally and strongly proposed the ‘prokaryotae’ as an extremely specific and overwhelmingly typical taxon at the highest level to include essentially all microorganisms distinctly characterized by the presence of a definitive nucleoplasm free from both the fundamental proteins as well as the nuclear membrane. Inter-estingly, the ‘eukaryotes’ are invariably designated as a possible taxon occurring almost at the same highest level so as to include other protists, plants, and animals. Ultimately, Allsopp commanded that the aforesaid two taxon variants be christened as kingdoms, Prokaryotae and Eukaryotae.

 

The following members from the ‘Kingdom Prokaryotae’, namely:

 

(a) Actinomycetes

 

(b) Bacteria

 

(c) Rickettsia and Coxiella, and

 

(d) Spirochaetes

 

shall be discussed in an elaborated manner in the sections that follows.
