Flagellum location
A flagellum is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have from one to many flagella.

The flagellar motor is a remarkable nanomachine embedded in the bacterial cell envelope. More than 20 different proteins are required for the assembly of the motor, which can be divided into several morphological domains.
