Detailed explanation-1: -Protists are the eukaryotes that cannot be classified as plants, fungi or animals. They are mostly unicellular and microscopic. Many unicellular protists, particularly protozoans, are motile and can generate movement using flagella, cilia or pseudopods.

Detailed explanation-2: -The ciliates are protists that move by using cilia. Cilia are thin, very small tail-like projections that extend outward from the cell body. Cilia beat back and forth, moving the protist along. Paramecium has cilia that propel it.

Detailed explanation-3: -Ciliates are an important group of protists, common almost anywhere there is water-in lakes, ponds, oceans, rivers, and soils. About 4, 500 unique free-living species have been described, and the potential number of extant species is estimated at 27, 000–40, 000.

Detailed explanation-4: -Most of the members of the protists move through the help of cilia or flagella. The organism may contain either cilia or flagella, but not both locomotory structures. The protist, which moves with the help of cilia, is Podophyra.
