Bacterial cells can move by using flagella, which are long, whip-like structures that extend from the cell. These flagella rotate rapidly, creating a propeller-like motion that allows the cell to move through liquids such as water or nutrient-rich fluids. Some bacteria also move by using pili, which are thin, thread-like structures that help the cell attach to surfaces and crawl along them. In addition, some bacteria can move by using a gliding mechanism, which involves a coordinated movement of the cell wall and surface proteins. Overall, the ability to move is important for bacterial cells to find food, evade predators, and locate suitable environments to thrive.
