Question

Which part of sperm gives or provides energy for the movement of sperm?

• A. Head
• B. Middle piece
• C. Tail
• D. All of the above

Answer 1

Answer: (B)

Middle piece

The sperm cell consists of a head, a middle piece and a tail. The head contains the nucleus with densely coiled chromatin fibers, surrounded anteriorly by an acrosome, which contains enzymes used for penetrating the female egg. The midpiece has a central filamentous core with many mitochondria spiraled around it, used for ATP production for the journey through the female cervix, uterus and uterine tubes. The tail or flagellum executes the lashing movements that propel the spermatocyte. So, the middle piece provides energy for the movement of sperms.

Therefore, the correct answer is option B.
