What is a protist cell?
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).
How do you identify a protist cell?
A few characteristics are common between 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 is a protists cell structure?
Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
Are protists single-celled?
Protists vary greatly in organization. Some are single-celled; others are syncytial (coenocytic; essentially a mass of cytoplasm); and still others are multicellular.
What is a protist quizlet?
protist definition. any organism that is not a plant, animal, fungus, or a prokaryote.
How do you classify protists?
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.
Are protists cell walls?
Protista. Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won’t be.
What types of cells are protists?
Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues. They could be viewed as those eukaryotes that cannot be classified as one of the other cell types. They include the one-celled animal-like protozoa, one-celled algae, slime molds and water molds.
Is protists unicellular or multicellular?
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.
What is the scientific name for a protist cell?
The scientific name of protists. Amoeba. Amoeba proteus.
