It was Haeckel, who first and foremost in the year 1866 vehemently suggested that the microorganisms
present in the particular kingdom,
Protista,
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 thehighest 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. Interestingly,
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
