Textbook Question
Chapter 59, Problem 1PL
Sperm are produced in the
a. seminiferous tubules.
b. interstitial cells.
c. epididymis.
d. ductus deferens.
Expert Solution & Answer
Summary Introduction
Introduction :
The reproductive system of a male is composed of external sex organs and organs in the pelvis region that helps in the reproduction of new offspring. The production of sperm is the main motive of male reproductive system. This system includes various organs, such as, testes, penis, ducts and glands, and epididymites.
Answer to Problem 1PL
Correct answer :
Option (a), seminiferous tubules.
Explanation of Solution
Explanation/justification for the correct answer :
Option (a) is seminiferous tubules. Seminiferous tubules are the site where sperms are produced and matured and become ready to fuse with woman’s egg. Hence, this option is correct.
Explanation for incorrect answer :
Option (b) is interstitial cells. Interstitial cells are responsible for the production of androgen hormone in the males. Hence, this option is incorrect.
Option (c) is epididymis. Epididymis is a coiled shaped tube that stores sperm and then transport it to testes. Hence, this option is incorrect.
Option (d) is ductus deferens. The ductus deferens is a tube that carries sperm from the epididymisto the ejaculatory duct. Hence, this option is incorrect.
Conclusion
Option (a), seminiferous tubules.
