A bacterium with tuft of flagella at both poles is called_____________?
Correct answer: D. Amphitrichous
- A. Lophotrichus
- B. Monotrichous
- C. Peritrichous
- D. Amphitrichous
Explanation
A bacterium with tufts of flagella at both poles is amphitrichous, since “amphi” indicates both ends. Students may choose lophotrichous because that term also describes a tuft of flagella, but lophotrichous refers to a tuft at one pole rather than at both poles.
