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).
These organisms are not plants, animals, bacteria, or fungi. Protists are a very diverse group of organisms. They are basically all the organisms that don't fit into the other groups. Characteristics of Protists. Protists as a group have very little in common. They are eukaryotic microorganisms with a fairly simple cell structure. Other than this, they are any organism that is not a plant, animal, bacteria, or fungus.
