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
NOTE: The current system of classification for eukaryotes has been changed. In 2005, based on new phylogenetic data the kingdom Protista was split into 5 supergroups. Protists belong to the Kingdom Protista, which include mostly unicellular organisms that do not fit into the other kingdoms. Characteristics of Protists. 1  mostly unicellular, some are multicellular (algae) 2  can be heterotrophic or autotrophic.  most live in water (though some live in moist soil or even the human body)
