Identify a structure that plays a role in motility.

Correct option is B

The correct answer is: (b) Flagella
Explanation:
· Flagella are whip-like structures that provide locomotion to cells, especially in bacteria and sperm cells.
Information Booster:
· Made of protein flagellin.
· Found in prokaryotes and eukaryotic gametes.
· Help bacteria move toward nutrients or away from toxins.
· Can be single or multiple flagella.
· Movement powered by proton motive force (in bacteria).
· Part of motility organelles.
Additional Information:
· Pili – Used for attachment, not movement.
· Cilia – Involved in movement but not as primary as flagella.
· Plasmid – Circular DNA, not for motility.
