Kingdom Protista: Definition, Characteristics & Examples Characteristics of Protists. Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. Kelp, or 'seaweed,' is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems.ingdom Protista contains the protists, or all the organisms that do not fit into the other kingdoms of life. Protists can be heterotrophic or autotrophic, mobile or immobile, single-celled or multi-celled, solo or a member of a colony. They are categorized into three main categories based on how they obtain nutrients.

Protist 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.any protists are flagellate, for example, and filter feeding can take place where the flagella find prey. Other protists can engulf bacteria and other food particles, by extending their cell membrane around them to form a food vacuole and digest them internally, in a process termed phagocytosis.

- Protist Characteristics: Protists are so small that they do not need any special organs to exchange gases or excrete wastes. They rely on simple diffusion, the passive movement of materials from an area of high concentration to an area of low concentration, to move gases and waste materials in and out of the cell.

Protist In all biological taxonomy schemes, protists (/ˈproʊtɨst/) were a large group of diverse eukaryotic microorganisms, mainly unicellular animals and plants, that do not form tissues. Formerly, these were assigned to the now-obsolete kingdom Protista.rotists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.

Protist Organisms These organisms are eukaryotes, meaning they are made up of single or multiple cells which all contain a nucleus enclosed by a membrane. The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi.

- This group contains plant-like, animal-like, and fungus-like organisms. This grouping is not based on evolutionary relationships but is more a grouping of convenience — the protists are the eukaryotes that aren’t plants, animals, or fungi.here will likely be changes in this grouping as the science of classification progresses. The majority of organisms classified as protists are unicellular though there are a few multicellular organisms. For example, kelp (“seaweed”) is technically a protist even though it is multicellular.

Explain how protists differ from other organisms? This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction.Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.rotists are simply organisms that don't fit into any of the other kingdoms. The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes.

Protists The protist kingdom includes protozoa and algae. (Two groups of fungi with similar characteristics to protozoa, myxomycetes and oomycetes, have been classified as protists.). Unicellular protozoa and algae are unicellular eukaryotes.
