Question

Peritrichous bacteria have ________.

• A. Flagella all over the body
• B. Tuft of flagella at one end
• C. Tuft of flagella at both ends
• D. Single flagellum at one end

Answer 1

The correct option is A Flagella all over the body

A. Flagella all over the body

Solution : There are four types of flagellar arrangements based on the number and placement of flagella on the cell. Multiple flagella randomly distributed all over the body of the bacterial cell is called peritrichous bacteria. It is self-propel in fluids by using specialized motors to rotate multiple helical filaments. The rotation of each motor is transmitted to a short flexible segment called the hook which in turn transmits it to a flagellar filament, enabling swimming of the whole cell.

So, the correct answer is option A.
