Principle: The ability of an organism to move by itself is called motility. Motility is closely linked with chemotaxis, the ability to orientate along certain chemical gradients. Eucaryotic cells can move by means of different locomotor organelles such as cilia, flagella, or pseudopods.bjectives: 1  To gain expertise in determining the motility of living bacteria. 2  To learn about the different methods of motilty determination. 3  To understand the biochemical process of hydrogen sulfide production by bacteria along with motility.
