Flagellum
Step-by-step explanation:
In the given question no image has been provided as well as no image has been found anywhere therefore this question is attempted based on previous knowledge.
The Prokaryotes are the unicellular organisms which were formed during the primitive time. Prokaryotic cells like bacteria obtain the energy to survive by consuming organic molecules. The prokaryotes to obtain the food evolved the cellular structure which helps in movement or locomotion called "Flagellum".
The flagellum is composed of the flagellin protein and microtubule filaments which helps in rotation of the flagellum in the clockwise and anticlockwise direction.
Thus, the flagellum is the correct answer.
