APili, used for attachment to surfaces
BFlagella, used for moving the cell
CPlasmids, made of extra DNA
DCapsules, used for surface coating
Answer & Solution
Correct answer: B. Flagella, used for moving the cell
1. Flagella are the appendages used for locomotion in the species that have them.
2. Pili are used for attachment to surfaces, including attachment to other prokaryotes.
3. Plasmids are extra-chromosomal DNA and are not appendages at all.
4. A capsule coats the cell and helps it stick, so it cannot drive movement.
