Protist (biology definition): Any of a group of eukaryotic organisms belonging to the Kingdom Protista. Protists include: (1) protozoa, the animal-like protists, (2) algae, the plant-like protists, and (3) slime molds and water molds, the fungus-like protists.
What are the 4 major groups of protists?
There are four major groups of protozoan:
- Flagellated Protozoans: They possess flagella for locomotion.
- Amoebid Protozoans: They develop pseudopodia which are temporary protoplasmic outgrowths.
- Sporozoans: All sporozoans are endoparasites.
- Ciliated Protozoans: Ciliates are protozoan protists.
What are 3 types of protists?
Although protozoa are not animals, they are thought to be the ancestors of animals. Three types of animal-like protists are paramecium, euglena, and amoebas.
What are 4 characteristics of protists?
Characteristics of Protists
They are eukaryotic, which means they have a nucleus. Most have mitochondria. They can be parasites. They all prefer aquatic or moist environments.
What are the types of protists?

What are 5 protists?
8.7: Protists and Human Disease
- Trypanosoma Protozoa.
- Giardia Protozoa.
- Plasmodium Protozoa.
What is the most common type of protist?
1 Answer
- Ameoba: Amoeba is an animal-like protist that can be found in soil as well as in freshwater and marine environment. Amoeba is unicellular and lack flagella.
- Algae: Algae are plant like photosynthetic protists carrying out probably 50→60% of all photosynthesis on earth.
What are 2 examples of protists?
Protists are simple eukaryotic organisms that are neither plants nor animals or fungi. They can be either autotrophic or heterotrophic in nature. Their cells possess a nucleus and membrane-bound organelles(eukaryotic organisms). Examples are Plasmodium, slime moulds, euglena.
What are protists 10 examples?
Algae, amoebas, euglena, plasmodium, and slime moulds are examples of protists. Algae, diatoms, dinoflagellates, and euglena are only a few examples of photosynthesis-capable protists.
What are the 6 classifications of protists?
The emerging classification scheme groups the entire domain Eukaryota into six “supergroups” that contain all of the protists as well as animals, plants, and fungi (Figure 13.15); these include the Excavata, Chromalveolata, Rhizaria, Archaeplastida, Amoebozoa, and Opisthokonta.
What are protists?
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12 (opens in new tab).
What are 5 facts about protists?
Interesting Facts about Protists
- Many protists act as pathogens to humans.
- The disease malaria is caused by the protist Plasmodium falciparum.
- If an amoeba is cut in half, the half with the nucleus will survive, while the other half will die.
- The word “pseudopod” comes from Greek words meaning “false feet.”
What is protists in biology?
protist, any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.
How many classes of Protista are there?
three groups
Ans: The kingdom Protista is classified into three groups namely, Plant-like Protists, Fungi-like Protists and Animal-like Protists.
What are 7 diseases caused by parasitic protists?
(2012b), Torgerson and Mastroiacovo (2013), World Health Organization (2013).
- 1.1. Malaria. Malaria is the most significant of the protozoan parasites that infect man.
- 1.2. African trypanosomiasis.
- 1.3. Chagas disease.
- 1.4. Leishmaniasis.

- 1.6. Cryptosporidiosis.
What is another name for protist?
protozoa
Another name for protists is protozoa.
What are the 7 plant like protists?
Examples of Plant-like Protists. The 7 major groups of algae are red algae, green algae, brown algae, fire algae, golden-brown algae, yellow-green algae, and euglenids.
What are 5 protists that cause disease?
Some severe diseases of humans caused by protists (primarily blood parasites) are Malaria, Trypanosomiasis (African sleeping sickness), Leishmaniasis, Toxoplasmosis, and Amoebic dysentery.
Are protists bacteria?
A protist is a one- or many-celled organism that lives in moist or wet surroundings. Unlike bacteria, protists’ cells are eukaryotic. These organisms have a membrane-bound nucleus and other membrane-bound structures in their cytoplasm.
Is algae a protist?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.
What are 2 examples of harmful protists?
Harmful Protists:
- They cause disease in their hosts or failure of crops.
- Example- Trypanosoma (causes sleeping sickness), Giardia (causes Giardiasis, a gastrointestinal infection), and Plasmodium (causes malaria).
