vlada-n [284]

Answer:

The correct answer is number one: <em>Filamentous rotating structures that provide motility may be singular, paired or scattered.</em>

Explanation:

Flagella are organelles defined by function rather than structure.

The primary function is that of locomotion but also being sensitive to chemicals and temperatures outside the cell.

Helicobacter pylori is a good example of flagella: It uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium.

Sperm cell is a good example, which uses its flagellum to propel itself through the reproductive tract of females.
