The figure shows the structure of
the human spermatozoon. Which letter indicates the
acrosome? (A) B, (B) A, (C) E, (D) C, (E)
D.
Let’s identify each structure by
starting from one end of the sperm and working our way to the other end. The tail gives the sperm its
mobility and allows it to move. The midpiece contains many
mitochondria, which provide energy to power the movement of the tail. The neck region contains the
centrioles. These are structures used for
cellular division and are needed for the fertilized egg to divide. The nucleus contains the DNA of the
sperm that can be paired with the DNA of the egg to form the DNA of the zygote. The acrosome contains hydrolytic
enzymes that allow the sperm to digest the outer membrane of the egg during
fertilization.
Therefore, the option that
correctly identifies the acrosome is answer choice (D) C.
