Question

A bacterial flagellum is composed of

• A. Filament, hook and basal body
• B. Vesicles, tubules and lamellae
• C. Pili, Fimbriae and filament
• D. Hook, tubules and Fimbriae

Answer 1

The Correct Option is A

A bacterial flagellum is primarily composed of three main parts:

• Filament: The long, whip-like structure that extends from the bacterial surface and is responsible for the movement of the bacterium.
• Hook: A curved structure that connects the filament to the basal body, allowing the flagellum to rotate.
• Basal body: The motor complex that anchors the flagellum to the bacterial cell membrane and is responsible for the rotation of the flagellum.

Thus, the correct answer is (A) : Filament, hook and basal body.
