Answer:
tails of sperm
Explanation:
The structure highlighted represents the tails of sperm (see the attached image).
The image in itself represents a slide containing stained sperm cells. The cells have been stained in order to further enhance the visualization or cellular components of the sperm cells.
The sperm cell consists of a head and a tail. The head contains all the cellular components while the tail functions as a locomotive organ which enables the sperm cell to swim about. While the tails of some sperm cells on the slide are stained in the same purple color as the head, some tails are stained differently from the head in yellow color.
