It belongs to the class Ciliatea of the phylum Protista. Underneath the cell membrane, there exist a thin and clear layer of ectoplasm, which encloses the cytoplasm. Paramecium is its genus name, and there are several species of this protist, namely aurelia, bursaria, caudatum, trichium, etc. Bursaria feeds readily on a particular species of Paramecium called Paramecium bursaria. The whole body of this protozoan is covered with fine protoplasmic cilia, which are arranged in definite longitudinal rows; these structures serve as its locomotive organs. Here we found that the cytoplasmic streaming of paramecia was suppressed by such compression and then observed the process without compression in this work. They possess certain chemical sensors, which enable them to locate food sources. In contrast, treatment with nocodazole (10 microg/ml) resulted in discontinuation of cytoplasmic streaming in paramecia. Paramekes in Greek means oval, which is a sense of longer than its width-um is a neuter (not masculine or feminine) noun ending. Class Ciliates 4. Ciliates' bodies are covered with fine cytoplasmic hair-like structures called cilia. Paramecium can be classifiedinto the following phylum and sub-phylum based ontheir certain characteristics.
