What are 3 characteristics of protists?
What are 3 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 3 differences between bacteria and protists?
Bacteria and protists are unicellular organisms….Difference between Bacteria and Protists.
Bacteria | Protists |
---|---|
Bacteria are prokaryotes | Protists are eukaryotes |
Nucleus is absent | They possess a well-defined nucleus |
Genetic material is present in an irregularly shaped region called the nucleoid | Genetic material is present inside the nucleus |
What are the two categories of protists?
1 Answer. The animal protists are called protozoa. The plant protists are algae.
What are classification of protists?
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 is the role of bacteria in the ecosystem?
Bacteria play important roles in the global ecosystem. The cycling of nutrients such as carbon, nitrogen, and sulfur is completed by their ceaseless labor. Organic carbon, in the form of dead and rotting organisms, would quickly deplete the carbon dioxide in the atmosphere if not for the activity of decomposers.
What are characteristics of bacteria?
There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.
How do protists differ in structure from 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.
What do bacteria and protists have in common?
Both bacteria and protists have cell membranes made of chemicals called phospholipids. A phospholipid in a bacterium or a protist has a water-soluble group at one end and a water-insoluble tail at the other, so the cell membranes of bacteria and protists are constructed from a bilayer of phospholipids.
What is the difference between bacteria and Protista?
A eukaroytic organism can be unicellular or multicellular; most (but not all) protists are actually unicellular. Unlike bacteria, protists have specialized organelles, including a true nucleus confined by a nuclear membrane. This compartmentalization differentiates protists from bacteria.
