Protists: Overview Protists are a kind of life traditionally classified in the kingdom Protista. Newer taxonomic organizations will classify some protists in the kingdom of Chromista, but they are still protists. Most protists are unicellular; however, they can be multicellular organisms. Protist...
TAXONOMY SYSTEM – KINGDOMProtists are primarily minuscule single-celled, unicellular organisms. Either prokaryotes or eukaryotes make up all living things. Examples of prokaryotes include bacteria and archaea. Eukaryotes include animals, plants, fungi, and protozoa. A fungus is a eukaryote. Fungi ...
However, unlike stromatolites, which feature a layered structure, thrombolites feature no such structure, instead appearing as a clumpy mess. The theory goes that protists like amoebas and other forams led to the rise in thrombolites and the downfall in stromatolites. They did this by ...
Vector transmissioninvolves a parasite using two hosts of different species. Common examples of vector-transmitted parasites include protists (Plasmodium,Trypanosmaand more), viruses and bacteria. Trophically transmitted parasitesalso need two or more hosts. The main host, typically a vertebrate, eats ...
This glutamate residue is strongly conserved in VDAC1 and VDAC2 within the animal kingdom and less conserved in VDAC3. The corresponding residue at this position in fungi is a conserved neutral glutamine. In plants, the residue found at the equivalent position is markedly hydrophobic with a ...

Protozoan, organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protists and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore poss
Like plants and animals, fungi arose from protists and are now accorded a kingdom of their own. Load Next Page
In 1860, however, British naturalist John Hogg took exception to the imposition of the plant and animal categories on the protists and proposed a fourth kingdom, named Protoctista (the other three kingdoms encompassed the animals, the plants, and the minerals). Six years later German zoologist...
