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.

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.

What Are Protists? According to Simpson, protists can be photosynthetic or heterotrophs (organisms that seek outside sources of food in the form of organic material). In turn, heterotrophic protists fall into two categories: phagotrophs and osmotrophs.

What is a Protist / What are Protozoa? The taxonomic kingdom Protista is a collection of single-celled organisms that do not fit into any other category. Protists are a group made up of protozoa, unicellular algae, and slime molds. We will concentrate on the animal portion of this group: the protozoa (proto = first, zoa = animals). Protozoa are the oldest known group of heterotrophic life that consume and transform complex food particles into energy.

Notes: Kingdom Protista Protists are grouped into 3 general categories: 1  animal-like - referred to as protozoans (pro means 'first,' and zo refers to 'animals'..the first animals) 2  plant-like - referred to as algae. 3  fungus-like - referred to as slime molds and water molds.

Although there is a lot of variety within the protists, they do share some common characteristics.wo smaller cells result. Algae. All Those members of the protista kingdom which act like plants. Algaes are also found in the Moneran and Plant kingdoms. Possess more Plant-like characteristics. Other algaes are grouped with the monerans and others with plants.

Kingdom Protista Kingdom Protista is a diverse group of eukaryotic organisms. Protists are unicellular, some are colonial or multicellular, they do not have specialized tissue organization. The simple cellular organization distinguishes the protists from other eukaryotes.ingdom Protista are categorized into two taxons: Protozoans-animal-like single-celled organisms. Algae-plant-like single or multi-celled organisms. Animal-like Protists-PROTOZOANS. Protists that have resemblance to animals are known as protozoans. They in moist and watery enviroments.

- The Protists-Eukaryotic Organisms Kingdom Protista Single-celled, eukaryotic organisms are called protists. They are grouped together in Kingdom Protista. Those protists that are animal-like are put in Subkingdom Protozoa, and the protists that are plantlike belong to Subkingdom Algae.

Diseases Caused by Protists Protists are not animals, plants or fungi, but they are single- or multi-celled eukaryotes. Eukaryotes are single- or multi-celled living organisms, each of which contains a nucleus surrounded by a membrane. Some of them are parasites, which live on or in their host, causing harm to that host.

Importance of Protists The protists include organisms that are plant-like (such as algae), organisms that are animal-like (such as amoebas), and organisms that are fungus-like (such as slime molds). It turns out that protists from each of these groups are important to life on Earth.

Protist Some protists, sometimes called ambiregnal protists, have been considered to be both protozoa and algae or fungi (e.g., slime molds and flagellated algae), and names for these have been published under either or both of the ICN and the ICZN.ther protists include pathogenic species such as the kinetoplastid Trypanosoma brucei, which causes sleeping sickness and species of the apicomplexan Plasmodium which cause malaria.

- The protists are a diverse group of organisms. In a sense, they are defined by what they aren't. Protists are eukaryotes that are not animals, fungi, or plants. In fact, these other groups probably evolved from a protist-like ancestors. We will be looking at a subset of the protists that are photosynthetic.econdary endosymbionts: the dinoflagellates and the heterokonts. These groups are also photosynthetic, but they got their chloroplasts by capturing red algae, green algae, or other eukaryote organisms that already had a chloroplast, but not directly from the capture of cyanobacteria.

- Today, scientists call these single-celled organisms protists. • Protists include all organisms with cells having nuclei and not belonging to the animal, plant, or fungi kingdoms. In other words, protists may be considered a collection of leftover organisms. There are six types of plant-like protists. • Plantlike protists, called algae, obtain their energy from sunlight. Like plants, algae use the Sun’s energy, water, and carbon dioxide from the air or water to produce food.

protist Gregory G. Dimijian, M.D./Photo Researchers. Protozoans, algae, and slime molds belong to a group of living things called protists, or protoctists. Protists are not animals, plants, fungi, or bacteria. Many protists are so small that people can see them only through a microscope. There are thousands of different species, or types, of protist. Many types live in water, both in oceans and in freshwater.

- Making the world better, one answer at a time. Protists are both heterotrophic or autotrophic. the former means that they have to find their food, and the latter means that they make their own food (like through photosynthesis).ingdom Protista are very small, and the smallest of the  Eukaryotes. They are either multicellular, unicellular, or  colonial, and are not plants, animals, or fungi.

Ciliates have permanent contractile vacuole pathways and pores where amoebas will release them from any point along the surface of its body.
