What is the main and larger locomotory structure of bacteria?

0
A) Pili
B) Flagellum
C) Cilia
D) Pseudopodia

Correct Answer: B) Flagellum

• The main and largest locomotory structure used by most motile bacteria is the Flagellum. • It is a long, whip-like biological appendage that rapidly rotates to propel the bacterium forward. • Cilia are much shorter, hair-like structures typically found in eukaryotic cells, not in typical bacteria. • Pili are used primarily for cellular attachment and genetic exchange rather than actual physical movement.
