What are the 4 major groups of protists?
Major Groups of Protists
- Chrysophytes. This group comprises of the diatoms and golden algae (desmids).
- Dianoflagellates. These organisms are usually marine and photosynthetic.
- Euglenoids. These are mostly freshwater organisms.
- Slime Moulds. Slime moulds are saprophytic protists.
- Protozoans.
What are the main categories of protists?
Protists are a diverse kingdom, including all eukaryotic organisms that are neither animals, nor plants, nor fungi. For classification, the protists are divided into three groups: animal-like protists, plant-like protists, and fungi-like protists.
What is a group of protists called?
Red Algae. Red algae, or rhodophytes, are primarily multicellular, lack flagella, and range in size from microscopic, unicellular protists to large, multicellular forms grouped into the informal seaweed category.

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.
Whats the definition of protists?
Definition of protist
: any of a diverse taxonomic group and especially a kingdom (Protista synonym Protoctista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (such as slime molds)
What organisms are grouped in protists?
The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi. Organisms in the Protista kingdom include amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds.
What are the four main types of fungi?
Fungi are usually classified in four divisions: the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi).
What are the two groups of protists?
1 Answer. The animal protists are called protozoa. The plant protists are algae.
How many protists are there?
There are thought to be between 60,000 and 200,000 protist species, and many hav e yet to be identified. Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems.
What are the 3 main groups of kingdom Protista?
How Protists Are Defined. Protists are defined by how they obtain nutrition and how they move. Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists.

What is Protista in biology?
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 characteristics of protists?
Summary
- Protists have nuclear membranes around their DNA.
- Many protists live in aquatic habitats, and most are motile, or able to move.
- Protists have complex life cycles that may include both sexual and asexual reproduction.
- Protists get food through ingestion, absorption, or photosynthesis.
Why are protists their own classification?
Protists are also classified based on some of the following traits: The presence or absence of certain organelles such as mitochondria and chloroplasts. The number of membranes that surround the chloroplast (two, three, or four). The types of chlorophylls and accessory pigments in the cell.
What is the Protista kingdom quizlet?
Define protist. Single celled or simple multicellular eukaryotic organisms that generally do not fit into any other kingdom.
What defines a protist?
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.
