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.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
