Vorticella campanula Unknown authority :: Algaebase

Before division of the organisms commences, the body of the organism shortens as it increases in breadth. This is then followed by the division of the nucleus where the macronucleus divides amitotically while the micronucleus divided mitotically. This is accompanied by the constriction of the organisms that ultimately divided the organism into two or more organisms.

While the parent organism divided to form two or more Vorticella, it is worth noting that only one of the new organisms retains the original vorticella campanula. This leaves the other to develop new cilia temporary cilia and ultimately a new stalk through which it can attach to another substrate or surface.

Binary fission of such Peritrichia as Vorticella has been shown to be unique compared to other ciliates given that it is often unequal and longitudinal in that it runs along the oral-aboral axis of the organism.

Diagrammatic representation of Longitudinal Binary Fission: Longitudinal Binary Fission diagram. As binary fission begins, the peristome first closes up as the body bell of the organism shortens and increases in breadth transverse elongation. The contractile pulsates during the division while the macronucleus shortens and condenses as it moves vorticella campanula the middle of the cell transversely.

As division continues, constriction begins at the anterior end of the cell vorticella campanula gradually divided the cell down its length from the peristome and towards the stalk.

This ultimately divided the organism into two unequal parts with one of the daughter cells being smaller.

Whereas the larger cell retains a stalk with which it can remain attached to a surface, the smaller one lacks a stalk but develops vorticella campanula cilia at its posterior.

Compared to the larger cell with a stalk, the smaller cell vorticella campanula more cylindrical in shape and is known as a teletroch.

Using the aporal cilia, the cell then swims away and attaches to a surface through its scopula at its aporal end. The vorticella campanula is also responsible for producing a new stalk for the daughter vorticella campanula that allows the organism to remain attached to the surface.

Vorticella Campanula: Habitat, Structure and Locomotion

Over time, the cylindrical vorticella campanula develops into a bell shape as the organism matures. This is divided into two main phases that include: Formation of micro and macro-conjugants This phase involves a binary fission process that produces vorticella campanula larger and smaller cell unequal cells.

Here, the smaller cell which may be more than one in some cases is known as the micro-conjugant. The body of Vorticella campanula vorticella campanula like an inverted bell. The detailed structure of the bell is described below: The margin or rim of the broad free end of vorticella campanula bell is thickened and is termed as peristomial collar or lip.

Inside the peristomial collar is a narrow, shallow, circular and marginal depression called the peristome vorticella campanula oral groove.

The peristome surrounds a broad, slightly convex circular central disc, the peristomial disc or oral disc that seems to close the opening of the bell. The peristomial vorticella campanula is fused with the collar on one side with the result the peristome does not form a complete ring.

The peristomial disc can vorticella campanula withdrawn when the peristome contracts and covers it. Between the peristome and the peristomial disc is a permanently open sunken space on the left side, it is called a vestibule or infundibulum.

From the vestibule a narrow cytopharynx leads inwards. The cytopharynx has vorticella campanula cilia and it opens into the endoplasm.
