motility — the ability to move spontaneously and actively, consuming energy in the process

tiny bacteria cells move actively in different directions through the water, propelling themselves with their flagella. Each bacterium changes direction spontaneously, creating swirling patterns as they consume nutrients. The movement requires energy as the cells actively navigate toward food sources. A scientist observes excitedly while pointing at the display screen showing the self-directed movement. Another researcher takes notes as they watch the organisms demonstrate their ability to move independently. the ability to move spontaneously and actively, consuming energy in the process
