What does a protist cell look like?
What does a protist cell look like?
The cells of protists are among the most elaborate and diverse of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, similar to ferns.
Which cells are protists?
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
What is an example of a protist cell?
Examples of protists include algae, amoebas, euglena, plasmodium, and slime molds. Protists that are capable of photosynthesis include various types of algae, diatoms, dinoflagellates, and euglena. Photosynthetic euglena are similar to plant cells in that they contain chloroplasts.
What are the functions of protist?
Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals and can cause deadly human diseases or destroy valuable crops.
Is a protist a prokaryote?
Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.
What are the characteristics of a protist?
Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
What is the most common 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 is another name of Protista?
“Protista”, “Protoctista”, and “Protozoa” are therefore considered obsolete. However, the term “protist” continues to be used informally as a catch-all term for eukayotic organisms that are not within other traditional kingdoms.
What are facts about protist cells?
are classified under Protists. They have a well-defined nuclear membrane and also contain mitochondria and some have chloroplast.
What are the three cell types of protist?
those that are animal-like and those that are fungus like.
What is a protist cell made up of?
Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell . The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
What do the cells of Protists contain?
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.
