Question

1. what part of the bacterial cell helps it move?

Explanation:

Bacterial cells use flagella (singular: flagellum) for movement. Flagella are long, whip - like structures that rotate, propelling the bacterium through its environment. Some bacteria may also use pili for a type of movement called twitching motility, but flagella are the primary structure for locomotion in most motile bacteria.

Answer:

The flagellum (or flagella, if multiple) is the part of the bacterial cell that helps it move. Some bacteria can also use pili for twitching motility, but flagella are the main structure for locomotion in most motile bacteria.
