F. Mueller, MÃ¼ller. C. G ehrenberg And Felix. FÃ©lix dujardin the first groups used to classify microscopic organism Were the animalcules And. the infusoria
L iving organisms are subdivided into 5 major kingdoms, including the Monera, the Protista (Protoctista), the Fungi, the Plantae, and the Animalia. Each kingdom is further subdivided into separate phyla or divisions. Generally animals are subdivided into phyla, while plants are subdivided into divisions.hese remarkable organisms are now placed in the domain Archaea. Other prokaryotes, including eubacteria and cyanobacteria, are placed in the domain Bacteria. All the kingdoms of eukaryotes, including Protista (Protoctista), Fungi, Plantae and Animalia, are placed in the domain Eukarya.
