Kurzthaler worked ...Flagella (singular, flagellum) are the locomotory structures of many prokaryotes. Most protozoa and some bacteria are motile. Protozoa use flagella, cilia, or pseudopods, whereas motile bacteria move only using flagella. The flagellum functions by rotation to push or pull the cell through a liquid medium.Recall that prokaryotes (Figure 22.2.2 22.2. 2) are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus but instead generally have a single chromosome—a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.The jiggling movement seen in some nonmotile bacteria that are incapable of self-propelled movement is due to the bombardment of the bacteria by water molecules. This so-called Brownian motion is not considered to represent bacterial movement. There are several types of bacteria movement. The most common occurs by the use of appendages called ... One of the most common bacterial movements occurs by the use of appendages called flagella.
