Stentors are indeed unicellular organisms.
the examples of unicellular organisms are BACTERIA, CHLASMYDAMONAS, EUKARYOTES (EUKARYYOTA).
All prokaryotic organisms are unicellular. Eukaryotic organisms are multicellular
Unicellular,filamentous and photosynthetic organisms are ALGAE
Bacteria are unicellular organisms that do not have a nuclei.
Unicellular protists, also known as micro-organisms, need oxygen to survive. They obtain oxygen by diffusing it across the cell membrane into the cell.
Diffusion and osmosis.
Cells do the same, or very similar things, whether they are part of a unicellular organism or a multicellular organism; they have a metabolism, they consume nutrients and oxygen, they have waste products, etc.
Most of the unicellular organisms reproduces asexually.
Diseases do not cause unicellular organisms; unicellular organisms cause diseases.
Colonies of unicellular organisms can work together.
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
If they're not using their cell, I'm not sure what else they would be using. There's only one cell to be used. If you're asking whether there is a "breathing mechanism" within the cell, then the answer is no. Unicellular organisms don't need an extensive respiratory system like multicellular organisms. Moreover, unicellular organisms couldn't "breathe" because no organelle supports such a thing. Instead, unicellular organisms get oxygen just through diffusion. Because unicellular organisms are small, the diffusion of oxygen into the cell is sufficient for cell respiration. In contrast, larger multicellular organisms can't obtain oxygen through diffusion alone because the oxygen couldn't "get" to every cell.
Unicellular organisms evolved first; and from them evolved the multicellular organisms. But that leads onto another question as to why multicellular organisms evolved.
Stentors are indeed unicellular organisms.
Not all kingdoms include unicellular organisms. The kingdoms that do not have unicellular organisms include the plantae and animalia kingdom.
