Bursaria, on the other hand, represents cells that are \"slipper\" shaped. However, … ADVERTISEMENTS: 2. Unlike amoeba, paramecium has a distinct and permanent shape and certain areas of cytoplasm, (cell organelles), are specialised to carry out specific functions. (see fig.). Paramecium is a ciliate protozoan. Any of various freshwater protozoans of the genus Paramecium that are usually oval in shape and that move by means of cilia. Paramecium covered with cilia, which allow it to move about and to feed on bacteria. As we already discuss above that P. caudatum has two types of nuclei one is macronucleus and the second one is micronucleus.

But there are many species of paramecium exhibit on the earth having different numbers of nuclei. It is believed that the discharge process of trichocysts consists of an infolding of the lattice of trichinin fibres. Each vacuoles lies near end the body, close to the dorsal or aboral surface. It includes the basal body, kinetodesmata, and trichocysts. Paramecium caudatum is the largest species measures between 170 micron to 290 micron long. Trichocysts of paramecium are very small in size, measuring about 4 micron in length. Vector diagram. Fig. Biology Teaching Resources.

Historically, based on cell shape, these organisms were divided into two groups: aurelia and bursaria, according to the \"The Biology of Paramecium, 2nd Ed.\" (Springer, 1986). Nutrition heterotrophic and reproduction by asexual as well as sexual methods. The diagram of paramecium shows ciliary slipper shaped elongated structure. Cilia are the hair-like fibre that covers the whole body. In 1959, Ehret and Powers revealed the polygons are appearing as corresponding regular series of cavity known as alveoli.

It occurs during favourable conditions when food is available in large […] Share Your PDF File In this article we will discuss about the structure of paramecium. Paramecium reproduces asexually by binary fission during favorable conditions in the following steps: (A) Paramecium stops feeding and starts to replicate its DNA, (B) Oral groove disappears.

Endoplasm possesses a large kidney shaped meganucleus and a small micronucleus. The cilia are used in locomotion and feeding. The waste material is produced in form of urea, calcium, potassium, sodium, etc. The body of paramecium distinguished into an oral or ventral surface and an aboral or dorsal surface. Paramecium is powered by a dual-core CPU – Macronucleus and Micronucleus On the side of a paramecium about mid-way is the oral groove (2). It primarily helps in locomotion and gathering food. The oral groove deeper in conical vestibule which forwarded in buccal cavity consist of oral cilia and basal mouth or cytosome (cyto= cell , stoma= mouth).
