How do some bacteria move?
A
They use flagella
B
They use cilia
C
They use pseudopods
D
They use blood, air, etc.
Explanation: 

Detailed explanation-1: -The bacterial flagellar motor is powered by the transmembrane electrochemical gradient of ions, namely ion motive force (IMF) and rotates the flagellar filament to generate thrust to propel the cell body. The maximum motor speed reaches 300 revolutions per second in E.

Detailed explanation-2: -The base of the flagellum (the hook) near the cell surface is attached to the basal body enclosed in the cell envelope. The flagellum rotates in a clockwise or counterclockwise direction, in a motion similar to that of a propeller.

Detailed explanation-3: -Prokaryotes, both bacteria and archaea, primarily use flagella for locomotion. Bacterial flagella are helical filaments, each with a rotary motor at its base which can turn clockwise or counterclockwise. They provide two of several kinds of bacterial motility.

Detailed explanation-4: -Gliding motility is the ability of certain rod-shaped bacteria to translocate on surfaces without the aid of external appendages such as flagella, cilia, or pili.
