Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.mong the pioneers in the study of the protists, which were almost ignored by Linnaeus except for some algae, were Leeuwenhoek, O. 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
Some biologists believe that Protista should be partitioned into three or more kingdoms. Similarly, kingdom Monera contains two very biochemically distinct groups of prokaryotes: archaebacteria, and eubacteria. A proposed system acknowledges this ancient evolutionary split by creating a higher level of classification, domain, above kingdom.
