What are the major groups of protists?
Major Groups of Protists
- Chrysophytes. This group comprises of the diatoms and golden algae (desmids). …

- Euglenoids. These are mostly freshwater organisms. …
- Slime Moulds. Slime moulds are saprophytic protists. …

What are the 3 classifications of protists how do they fall into this classification?
The protists can be classified into one of three main categories, animal-like, plant-like, and fungus-like. Grouping into one of the three categories is based on an organism's mode of reproduction, method of nutrition, and motility.
What are the three types of protists give an example of each?
Lesson Summary
- Animal-like protists are called protozoa. Most consist of a single cell. …
- Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. …
- Fungus-like protists are molds. They are absorptive feeders, found on decaying organic matter.

What are the 4 main protists?
Animal-like protists are also known as Protozoa. Some are also parasites. The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.
What are the 3 super groups of protozoans and describe each?
There are three main groups within the supergroup excavata – diplomonads, parabasalids and euglenozoans. Diplomanads and parabasalids have modified mitochondria and euglenozoans have unusual flagella. Diplomanads are single-celled protists with modified mitochondria called mitosomes.
What are the 3 structures that protists use to move?
Protists have three types of appendages for movement. As shown in Figure below, they may have flagella, cilia, or pseudopods (“false feet”).
What are the two major categories of protists?
1 Answer. The animal protists are called protozoa. The plant protists are algae.
What are the 3 structures of a protist that allow it to move?
Protists have three types of appendages for movement. As shown in Figure below, they may have flagella, cilia, or pseudopods (“false feet”).
What are 3 domains of life?
This phylogeny overturned the eukaryote-prokaryote dichotomy by showing that the 16S rRNA tree neatly divided into three major branches, which became known as the three domains of (cellular) life: Bacteria, Archaea and Eukarya (Woese et al. 1990).
How are the main groups of protists organized?
Protists were traditionally placed into one of several groups based on similarities to a plant, animal, or fungus: the animal-likeprotozoa, the plant-like protophyta (mostly algae), and the fungus-like slime molds and water molds.
What are alveolates and what 3 protists are found in this clade?
The alveolates (meaning "pitted like a honeycomb") are a group of protists, considered a major clade and superphylum within Eukarya. They are currently grouped with the stramenopiles and Rhizaria among the protists with tubulocristate mitochondria, the group being referred to as SAR.
What are the three types of protists and their characteristics?
For classification, the protists are divided into three groups:
- Animal-like protists, which are heterotrophs and have the ability to move.
- Plant-like protists, which are autotrophs that photosynthesize.
- Fungi-like protists, which are heterotrophs, and they have cells with cell walls and reproduce by forming spores.

Why are protists grouped together?
Organisms in the Kingdom Protista are very different from each other. They are grouped together partly because they just don't fit into any other kingdom.
What are the 3 domains and examples?
The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
What domain is Protista in?
domain Eukarya Protists is a kingdom that falls under the domain Eukarya.
How many groups are there in protists?
Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.
How many protists are there?
There are thought to be between 60,000 and 200,000 protist species, and many have 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 4 supergroups of protists?
The Stramenopiles include four different clades: 1) the Diatoms, 2) the Golden Algae, 3) the Brown Algae and 4) the Oomycetes (Water Molds). 1.
What are the four main groups of protozoans?
Protozoa are unicellular, heterotrophic, eukaryotic organisms comprising four organization types: amebae, flagellates, ciliates, and parasitic sporozoans.
What are three types of structures that help some protists move?
Motility of Protists This is the ability to move. Protists have three types of appendages for movement. As shown in Figure below, they may have flagella, cilia, or pseudopods (“false feet”). There may be one or more whip-like flagella.
How many groups of protists are there?
For classification, the protists are divided into three groups: Animal-like protists, which are heterotroph and have the ability to move. Plant-like protists, which are autotroph that photosynthesize. Fungi-like protists, which are heterotrophs, and they have cells with cell wall and reproduce by forming spore.
What is the 3 domain classification system?
The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
What the 3 main groups of life are and a brief description of each?
All of life can be divided into three domains, based on the type of cell of the organism: bacterium: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.
What cell type is Protista?
single-celled eukaryotes The kingdom Protista contains the single-celled eukaryotes in contrast to the bacteria which are examples of the prokaryotic cell type. Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues.
What are the 4 protists?
Animal-like protists are also known as Protozoa. Some are also parasites. The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.
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.
Which of the following is a protist?
Some of the organisms which are classified as protists are: Amoebas, Choanaflagellates; Ciliates; Dinoflagellates; Giardia; euglena; Plasmodium and slime molds. Paramecium is also classified as protist because of its eukaryotic nature. It is the genus of unicellular ciliated protozoa.
What are the supergroups?
Abstract. Nearly all of eukaryotic diversity has been classified into 6 suprakingdom-level groups (supergroups) based on molecular and morphological/cell-biological evidence; these are Opisthokonta, Amoebozoa, Archaeplastida, Rhizaria, Chromalveolata, and Excavata.
What are the major classes of protozoa?
Protozoans consist primarily of eukaryotic and single-celled organisms. They are represented by four major groups namely Flagellates, Ciliates, Sarcodina, and Sporozoans.
How are protozoans divided into major groups?
Protozoa can be divided into four phyla based on their locomotion: Mastigophora, Sarcodina, Ciliophora, and Sporozoa.
