1. Because there are too many organisms in the Protist Kingdom.
2. Some organisms are way different compared to each other.
There are 2 main reasons why scientists believe that the Protist Kingdom should be broken up.
One reason is that there are just way too many organisms in the kingdom. The second reason is that some organisms are just too different compared to one another
Protists are mostly the misfits that don't belong elsewhere. Thus, their characteristics and properties are somewhat nebulous and they don't form a cohesive group. It would be better for classification purposes to further divide the group.
Because Protista is a large and very diverse group of organisms and there is no one characteristic that they all share (besides being eukaryotes). They are often too different in a number of ways, so it's hard to classify them all into one single group.
Animalia. (Eukarya includes Protists, Animalia, Plantae, and Fungi)
They help us directly divide kingdoms into several groups.
The scientific theory should be changed.
There are several, and Enrico Fermi is just one.
Originally, the "protists" were either classified as "animal-like"/"protozoon" or "plant-like"/"algae", back when the only two kingdoms were Linnaeus' Regnum Animalia and Regnum Vegetablia. A lot of protists, though, did not really fit into either of these categories, including (for instance) the green euglena Euglena viridis. Like an animal, the green euglena is able to move freely (with its flagellum), eat other creatures, and detect light. Like a plant, though, the euglena typically photosynthesises (reverting to heterotrophy when dark), and has a cell wall (albeit a flexible one). Ernst Haeckel thus created a new kingdom, Protista, to include such "misfits". Over time, the two-kingdom system fell into disfavour and was replaced by the five kingdoms Monera, Protista, Plantae, Fungi, Animalia.Recently, though, improved genetic techniques revised taxonomy again. The current trend is to base taxonomic groups on evolutionary relationships. As Protista was created as a wastebasket taxon, and its members were so incredibly diverse, it has since been split into several kingdoms, including Amoebozoa (amoebae and most slime moulds), Choanozoa (single-celled immediate relatives of the animals), Chromalvelota (ciliates, apicomplexans, brown algae, diatoms, etc.), Excavata (euglenae, deer fever, etc.), Rhizaria (radiolarans, forimaferians, etc.), and various others. We're still very far from a true consensus, so many just still use "Protista".
There are in many kingdoms. But many of protists are like that
protista - apex
Animalia. (Eukarya includes Protists, Animalia, Plantae, and Fungi)
They can belong to several kingdoms. While plants are the most obvious choice, some organisms in the kingdom Eubacteria carry out photosynthesis as do some protists.
Protista
Sundiata conquered and united several smaller kingdoms to form Mali.
No, viruses are in a group of their own. They are not living organisms since they don't carry out all the 7 vital functions so their group isn't officially a kingdom.
There are many types. Plants,fungi and some protists arethem
Acellular slime molds
There are several examples of domains... Domain Bacteria Domain Archaea Domain Eukarya which consists of different kingdoms: Protists Plantae Fungi Animalia
Generic name for animal-like protists would be Protozoa.
Several small kingdoms (were united).
