Detailed explanation-1: -Paramecium caudatum is a species of unicellular protist in the phylum Ciliophora. They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. The cilia are used in locomotion and feeding. The species is very common, and widespread in marine, brackish and freshwater environments.

Detailed explanation-2: -Paramecium has around 4, 000 motile cilia on its surface arranged in longitudinal rows, beating in waves to ensure movement and feeding. As with cilia in other model organisms, direction and speed of Paramecium ciliary beating is under bioelectric control of ciliary ion channels.

Detailed explanation-3: -Ciliate is a group of protozoans that can move with the help of cilia only. Paramecium is the key member of this group which shows isochronous or metachronous rhythms of locomotion.

Detailed explanation-4: -Paramecium are unicellular protozoans classified in the Genus Paramecium, and the Kingdom Protista.

Detailed explanation-5: -Paramecium (/ˌpærəˈmiːʃ(i)əm/ PARR-ə-MEE-sh(ee-)əm, /-siəm/-⁠see-əm; also spelled Paramoecium, plural Paramecia) is a genus of eukaryotic, unicellular ciliates, commonly studied as a model organism of the ciliate group.
