WebMar 8, 2024 · A clockwise motion makes the bacteria turn around because it causes a tumbling motion. Flagella have more functions than just being a tool for movement, such as helping with infectivity, cell ... WebThe chaotic motion of the cell body, in reaction to a number of flagella which are rotating and in transition, constitutes the tumble. The induction of polymorphic transitions by mechanical force is confirmed by studies with motor and flagellar mutants, and with cells converted to curly flagellar phenotype by p-fluorophenylalanine.
