Paramecium: Species are commonly studied as model organisms

Paramecium species are commonly studied as model organisms of the ciliate group and have been characterized as the "white rats" of the phylum Ciliophora. [3] Paramecium were among the first ciliates to be observed by microscopists, in the late 17th century. Paramecium, genus of microscopic, single-celled, and free-living protozoans . Most species can be cultivated easily in the laboratory, making them ideal model organisms, well suited for biological study. Paramecium is a type of single-celled organism belonging to the group of eukaryotes. These organisms are called ciliates and are commonly studied to understand certain biological processes. Paramecia are found in various aquatic environments, such as freshwater, brackish, and marine habitats. Habit and Habitat Paramecium caudatum (Gr., paramekes =oblong+ L., caudata =tail) is a free-living organism which is one of the most common species of Paramecium having worldwide distribution. It is commonly found in freshwater, ponds, pools, ditches, streams, lakes, reservoirs, and rivers. It is usually found abundant in water containing decaying organic matters, in organic infusion, and in the sewage water. It thrives well in ponds or slowly running streams containing aquatic plants. It is ...
