Answer: Flagella can rotate 360 degrees.
Which of the following statements about bacterial flagella is true?

Bacterial flagella are helical filaments each with a rotary motor at its base which can turn clockwise or counterclockwise. They provide two of several kinds of bacterial motility. Archaeal flagella are called archaella and function in much the same way as bacterial

A flagellum is a lash-like appendage that protrudes from the cell body of certain cells termed as flagellates. A flagellate can have one or several flagella. The primary function of a flagellum is that of locomotion but it also often functions as a sensory organelle being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. Flagella vary greatly among the three domains of life bacteria …

Bacteria (/ b æ k ˈ t ɪər i ə / (); common noun bacteria singular bacterium) are a type of biological cell.They constitute a large domain of prokaryotic microorganisms.Typically a few micrometres in length bacteria have a number of shapes ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth and are present in most of its habitats.

Counter-clockwise rotation aligns the flagella into a single rotating bundle causing the bacterium to swim in a straight line; and ; Clockwise rotation breaks the flagella bundle apart such that each flagellum points in a different direction causing the bacterium to tumble in place.
