Are Stentor protozoa?
Stentor, genus of trumpet-shaped, contractile, uniformly ciliated protozoans of the order Heterotrichida. They are found in fresh water, either free-swimming or attached to submerged vegetation. Stentor assumes an oval or pear shape while swimming.
Is Stentor an algae?
They are multicellular, but they are smaller than many unicellular ones and much smaller than a Stentor. Stentor polymorphus and a few other species contain a single-celled green alga named Chlorella, which survives in the ciliate and performs photosynthesis. Stentor uses some of the food that the algal cells produce.
What does a Stentor eat?
bacteria
Stentor are omnivorous heterotrophs. Typically, they feed on bacteria or other protozoans. Because of their large size, they are also capable of eating some of the smallest multicelluar organisms, such as rotifers. Stentor typically reproduces asexually through binary fission.
How does a Stentor eat?
Stentors, like most ciliates, are filter feeders; passively eating whatever happens to be swept in their direction. They normally eat bacteria and algae, though large stentors are reported to opportunistically eat rotifers or anything else that they can catch.
Where is the mouth of a Stentor located?
Hairlike cilia lining the “trumpet” beat rhythmically to create currents that draw particles, bacteria, and other small protozoans, into the cytostome (mouth) of the stentor. Stentors are commonly found in most freshwater ponds, attached to vegetation or other surfaces where they generally spend their lives.

What kind of food does a Stentor eat?
Typically, they feed on bacteria or other protozoans. Because of their large size, they are also capable of eating some of the smallest multicelluar organisms, such as rotifers. Stentor typically reproduces asexually through binary fission. They can also reproduce sexually via conjugation.
Where are Stentor protozoans found in fresh water?
See Article History. Stentor, genus of trumpet-shaped, contractile, uniformly ciliated protozoans of the order Heterotrichida. They are found in fresh water, either free-swimming or attached to submerged vegetation.
How are Stentor protists able to eat bacteria?
Second, they move in unison to push water across the mouth area (or gullet). Tiny bacterial food particles are found in the water, so forcing water over the mouth area enable them to eat by picking the bacteria out. When attached to an organism, Stentor cells are trumpet-shaped.
What kind of food does the protozoan eat?
protozoan: Food selection. The large ciliate Stentor, for example, takes ciliates in preference to flagellated cells and algae, and discrimination increases as the animal becomes less hungry.
