Chapter 36, Problem 6A

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 6A

Correct answer:

The correct answer is option (A) Sperm cell storage and maturation.

Explanation of Solution

Explanation/justification for the correct answer:

Option (A) Sperm cell storage and maturation. The labeled part A of the diagram of testes describes sperm cell storage and maturation. In the epididymis, sperm maturation happens. The epididymis is also used to preserve sperm and to shield sperm from chemical damage. The male reproductive system ensures that sperm is produced, matured, stored, and ejaculated. The urethra exits all semen and urine. So, this is the correct answer.

Explanation for incorrect answer: 

Option (B) Sperm cell production. The labeled part A describes sperm cell storage and maturation. The labeled part A does not define sperm cell production. So, option (A) is incorrect.

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

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