Question

When a bacterium is said to be amphitrichous, it means that it has

• A. no flagella
• B. flagella at one end
• C. flagella at both ends
• D. flagella all around

Answer 1

The correct option is C flagella at both ends

A flagellum is a locomotory structure and its distribution varies from species to species. If it is absent, it is said to be atrichous. If it is at one end it is said to be monotrichous. If present at both ends, it is said to be amphitrichous and if it is all around then it is called peritrichous.
