Using a compound microscope, Jorge is able to see a single-celled organism moving rapidly in the field of view. He can just make out one long, whip-like structure that is undulating back and forth. Jorge has just identified:

Select one:
a. cilia
b. spindle fibers
c. a flagellum
d. chromosomes

The tail of a cell that is used to move around is called the Flagellum, so it's C.

A rotating structure called a **flagellum **has evolved specifically for bacterial movement.
What is Flagellum?
It employs PMF and rotates at a rate of several hundred** revolutions** per second. A** flagellum** is built using more than 40 genes, and for effective production, a scaffolding protein, capping proteins , and an export apparatus tailored for flagellar proteins are developed.
The number of **flagella, **the filament's helical handedness, and the **flagellar **motor's rotational orientation dictate each bacterial species' spectrum of behavior.
A flagellum is a protruding, lash-like organ found on some bacteria and eukaryotic cells (such as sperm cells). Latin's** flagellum means "whip" in English. There may be one or several flagella** on an organism.
Therefore, A rotating structure called a **flagellum **has evolved specifically for bacterial movement.

Jorge has identified a flagellum, which is a long, whip-like structure used by some cells for movement. Flagella enable organisms to swim and are characterized by their rotating motion. The correct choice is 'c. a flagellum.'
