What is the structure of flagella?

Answer 1

The structure of flagella includes the flagellar protein, flagellar motor, and hook. It also includes the flagellar filament and cap.

Answer 2

Flagella are whip-like appendages made up of a protein called flagellin. They consist of three main parts: the filament, hook, and basal body. The filament is the long, helical structure that extends from the cell and is composed of stacked flagellin molecules. The hook connects the filament to the basal body, which acts as a motor to rotate the flagellum and propel the cell.
