Question

The basal body of the flagellum is anchored into the

• A. Hook
• B. Outer membrane
• C. Cell wall
• D. Cell membrane

Answer 1

The correct option is D Cell membrane

The bacterial flagellum has 3 parts: Filament, hook and the basal body. The basal body constitutes the extreme basal part of the flagellum embedded in the plasma membrane; the hook represents a broader and thicker basal region of a flagellum with a sharp bend and passes out through the cell wall; and the filament is the thinner, elongated, terminal part. Bacterial flagellum structure allows it to spin like a propeller and thereby helps in bacterial movement.
