Protists and other single celled organisms move by either the use of Cilia, fagellae or by pseudopodia.Cilia are short hair-like structures which help the organism move with a wave like motion there are usually many over the animal's surface. Flagellae are single whip like organelles which propel the organism.rotists and other single celled organisms move by either the use of Cilia, fagellae or by pseudopodia.
Cilia are similar to flagella in structure and function, but a cilium is shorter and moves differently. A ciliated cell usually has hundreds or thousands of cilia, which move in unison like little oars.Sometimes a cell will also use cilia to funnel food into an oral groove. flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota. While all three types of flagella are used for locomotion, they are structurally very different.
