How Does the Flagella Work?

Flagella Work Through Rotational Motion of the Filament
In bacterial flagella, the hook at the bottom of the filament rotates where it is anchored to the cell wall and plasma membrane. The rotation of the hook results in a propeller-like motion of the flagella.

How does the flagella function?

Flagellum is primarily a motility organelle that enables movement and chemotaxis. ... In addition to motility, flagella possess several other functions that differ between bacteria and during the bacterial life cycle: a flagellum can, for example, participate in biofilm formation, protein export, and adhesion.

What does flagella do in simple terms?

A flagellum (plural: flagella) is a long, whip-like structure that helps some single celled organisms move. ... They help propel cells and organisms in a whip-like motion. The flagellum of eukaryotes usually moves with an “S” motion, and is surrounded by cell membrane.
