Chapter 36, Problem 5A

Summary Introduction

Introduction: 

Testes are responsible for developing testosterone that is the main male sex hormone and produces sperm. The seminiferous tubules are coiled within the testes. These tubules generate the sperm cells in a mechanism known as spermatogenesis.

Answer to Problem 5A

Correct answer: 

The correct answer is option (B) Sperm cell production.

Explanation of Solution

Explanation/justification for the correct answer:

Option (B) Sperm cell production. The labeled part C of the diagram of testes describes sperm cell production. Sperm cells are formed in structures called seminiferous tubules inside the testicles. It is transferred through the long seminiferous tubules until the sperm has matured and deposited in the epididymis of the testicles until it can escape the masculine body. So, this is the correct answer.

Explanation for incorrect answer: 

Option (A) Sperm cell storage and maturation. The labeled part C describes sperm cell production. So, option (A) is incorrect.

Option (C) Secretion of sugar. The labeled part C describes sperm cell production. It does not secrete sugar. So, this is an incorrect option.

Option (D) Production of FSH. FSH hormone is not secreted by the labeled C part of the image. So, this is an incorrect answer.
