Important Facts About Vorticella


Are you interested to know more about vorticella? Many times classroom instruction is not enough, leaving students with several unanswered questions. It is not practically possible for a teacher to pay attention to each and every student in a class. If you wish to learn more, consider hiring a private tutor who will answer all your queries. In this article, we will discuss regarding some of the interesting facts of vorticella:

For instance, it is quite interesting to note the behavioral pattern of this species. There are more than hundred diverse species of vorticella that are listed under kingdom protoctista and phyllum ciliophora. Each cell appears like a stalked ciliate, which is shaped as an inverted bell. There are also some other types of genera such as carchesium that look like vorticella. However they are quite different in shape and structure. Learning about the various facts of this organism will help you differentiate it from other similar types of genera.

The vorticella is a sessile organism, but the young ones can swim freely. The adults can also swim freely if the stalks are cut, or if they separate themselves from the substrate under the unfavorable conditions. It is amazing to note how the adult organisms attach themselves to the substrates with stalks.

One amazing fact is that its peduncle or stalk is capable of contracting; and the contractions are caused by the spasmoneme, which is the wavy filament present inside peduncle. The filament gets shortened when stimulated, and the stalk coils just like a spring.

The filament was earlier known as myoneme, before it was discovered that the chemical system administers the narrowing of spasmoneme. This is quite different from the system used by a true muscular fiber.

The spasmoneme actually consists of three cellular membranes, an outer sheath, and an extracellular matrix. The coiling of the stalk at the time of contractions is supposed to be a protection mechanism to defend vorticella from the various environmental hazards. The contractions also help the organism to capture food particles when it is hungry. When the food supplies are scarce, they need to find a new place. These organisms are often found in clusters, which create a tiny jelly-type mass that can be easily seen by the naked eye.

These were some important and interesting facts about vorticella. If you wish to learn more about it then consider hiring a private home biology tutor.
