What color is a Stentor?

What color is a Stentor?

The various species of stentor tend to be brightly colored. For example, Stentor coeruleus is blue in color. Other species are yellow, red, and brown. Stentor are one of the largest protozoa found in water.

Is a Stentor a prokaryote?

Finally, as we learned in the previous section, all protists are eukaryotic, meaning they have a defined nucleus. Because the Stentor organisms are relatively large for unicellular beings, they actually have a macronucleus that stretches the length of the body.

What does Stentor look like?

Stentor coeruleus is a very large trumpet shaped, blue to blue-green ciliate with a macronucleus that looks like a string of beads (dark connected dots on the left). With many myonemes, it can contract into a ball. It may also swim freely both extended or contracted.

What type of cell is a Stentor?

What is Stentor coeruleus? Stentor coeruleus is an astoundingly large (~1 mm long) single-celled pond organism with a distinct trumpet shape and a well-defined morphology (Figure 1).

What does Stentor mean?

1 : a person having a loud voice. 2 : any of a widely distributed genus (Stentor) of ciliate protozoans having a trumpet-shaped body with the mouth at the broad end and with the narrow end often attached to the substrate.

What does Vorticella mean?

Vorticella is a genus of bell-shaped ciliates that have stalks to attach themselves to substrates. The stalks have contractile myonemes, allowing them to pull the cell body against substrates. The formation of the stalk happens after the free-swimming stage.

What does Cyclops mean?

Cyclops, (Greek: “Round Eye”) in Greek legend and literature, any of several one-eyed giants to whom were ascribed a variety of histories and deeds. In Hesiod the Cyclopes were three sons of Uranus and Gaea—Arges, Brontes, and Steropes (Bright, Thunderer, Lightener)—who forged the thunderbolts of Zeus.

Is a Stentor heterotrophic?

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.

Why are the Stentor green?

In ornamental ponds or lagoons, Stentor can be very colorful – there can be green, blue and amethyst colored species. The green color is a result of ingested microscopic green algae. The algae live in symbiosis with the Stentor, i.e. the algae and Stentor mutually benefit from the close association.
