Question

multiple choice question
which of the following is the typical motility structure of bacteria?

flagella
fimbriae
pili
pseudopodia

Explanation:

To determine the typical motility structure of bacteria, we analyze each option:

• Flagella: Bacterial flagella are long, whip - like structures that rotate to enable bacterial movement, making them a key motility structure.
• Fimbriae: These are short, hair - like structures mainly used for attachment to surfaces, not for motility.
• Pili: Pili are involved in processes like conjugation (transfer of genetic material) and attachment, not motility.
• Pseudopodia: Pseudopodia are used for movement by some protists (e.g., amoeba) and not by bacteria.

Answer:

A. Flagella
