Question

Quizplus · Accepted Answer

Movement in bacteria is often referred to as run and tumble, and it may involve pili. Bacteria use pili to attach to surfaces or other bacteria, and some bacteria can use them to move across surfaces. During run and tumble, bacteria move in a straight line or run, then they tumble or change direction. This random movement helps bacteria explore their environment, find nutrients, and avoid harmful substances or predators.
