Does Stentor Digest Food?

When moving, the stentor is contracted into an oval or pear shape. Being single celled, there are no separate parts which make up a "mouth" or other organs. For digestion, the cell wall envelops the food, and separates to form a round bubble like "vacuole" within the cell.

Is Stentor heterotrophic or autotrophic?

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.

What is the movement of a Stentor?

As a unicellular protozoa, Stentor can be up to 2 millimeters in size, making them visible to the naked eye. They live in stagnant freshwater environments and feed on bacteria. They move and eat through the use of cilia, and they maintain their water balance with the use of a contractile vacuole.
