A eukaryotic cell usually has only one or two flagella. As in prokaryotes, the eukaryotic flagellum may be used in locomotion; one well known example of this is the sperm cell, in which the "tail" of the sperm (a flagellum) is used to propel the cell forward. However, all non-dividing eukaryotic cells contain a flagellum (or cilium), not only sperm cells. Stationary cells (such as kidney, intestine, and nerve cells) also contain flagella (cilia) which project from the cell body out into the extracellular environment. There, these flagella can serve in sensation or in the movement of extracellular fluid.
Monotrichous bacteria have a single flagellum (e.g., Vibrio cholerae). Lophotrichous bacteria have multiple flagella located at the same spot on the bacteria's surfaces which act in concert to drive the bacteria in a single direction. Amphitrichous bacteria have a single flagellum on each of two opposite ends (only one flagellum operates at a time, allowing the bacteria to reverse course rapidly by switching which flagellum is active). Peritrichous bacteria have flagella projecting in all directions (e.g., Escherichia coli).

Some species of bacteria (such as Spirochetes) have a specialized type of flagellum called an "axial filament" that is located in the periplasmic space, the rotation of which causes the entire bacterium to move forward in a corkscrew-like motion.

also spelled procaryote, any self-contained cell or organism that lacks internal unit membranes. Bacteria are among the best-known prokaryotic organisms. Prokaryotes lack a nuclear membrane and most of the components of eukaryotic cells. The cell membrane consists of a phospholipid unit membrane and constitutes the cell's primary osmotic barrier. The cytoplasm includes ribosomes that carry out translation and protein synthesis. The nuclear region usually consists of circular, double-stranded deoxyribonucleic acid (DNA). Many prokaryotes also contain accessory, self-replicating genetic structures, called plasmids, with additional dispensable cell functions, such as encoding proteins to inactivate antibiotics. The flagella are distinct from those of eukaryotes in design and movement. The organelles that are present, such as storage vesicles, are surrounded by a nonunit membrane consisting principally of proteins. See also eukaryote; bacteria.
