WebBacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells. In bacteria, chemical communication involves producing, releasing, detecting, and respondi … WebAug 29, 2024 · How do bacteria move? Many bacteria move using a structure called a flagellum. The flagellum is a long, corkscrew-like appendage that protrudes from the surface of the bacterium and can extend for a distance longer than the bacterial cell itself. A typical flagellum may be several thousand nanometers long and only 30 nanometres wide.
