Is Stentor heterotrophic or autotrophic?

Stentor is Omnivorous Heterotroph. Usually, they feed on bacteria or other protozoa. Due to their large size, they are also able to eat some of the smallest multicellular organisms, such as rotifers. Stentor usually reproduces asexually by binary fission.

Is Stentor free-living or parasitic?

Some ciliates also live on animals.Examples of ciliates include live freely Paramecia, Stentor polymorpha, Vorticella campanula and other forms and parasitic forms such as Balantidium coli. There are three types of ciliated protozoa. They are free-swimming ciliates, crawling ciliates, and stem ciliates.

What organelles does Stentor have?

Stentor has other organelles Ciliates. It contains two nuclei – a large macronucleus and a small micronucleus. The large core looks like a beaded necklace. Vacuoles (sacs surrounded by membranes) are formed as needed.
