A suffix is a letter or series of letters attached to the end of a word, word base, or prefix to produce a derivative word with a new meaning. There are many suffixes used by biologists in constructing scientific names and terminology.
Kingdom is the highest rank used in the biological taxonomy of all organisms. There are 6 kingdoms in taxonomy. Every living thing comes under one of these 6 kingdoms. The six kingdoms are Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia. Until the 20th century, most biologists considered all living things to be classifiable as either a plant or an animal. But in the 1950s and 1960s, most biologists came to the realization that this system failed to accommodate the fungi, protists, and bacteria. By the 1970s, a system of Five Kingdoms had come to be accepted as the model by which all living things could be classified. At a more fundamental level, a distinction was made between the prokaryotic bacteria and the four eukaryotic kingdoms (plants, animals, fungi, & protists).
Core Knowledge. Protists and fungi are microbes that are eukaryotic organisms. Protists include a variety of eukaryotic cells that do not fit into any other category of eukaryotes and are classified by the way they obtain nutrition.
