What are the functions of gonads and testes in vertebrates?
Understand the Problem
The question involves understanding the role and function of gonads and testes in vertebrates, focusing on gamete production, hormonal influence, and secondary sexual characteristics.
Answer
Gonads produce gametes and hormones; testes produce sperm and testosterone.
The gonads in vertebrates produce gametes (sperm in males, ova in females) and secrete hormones that influence body growth and secondary sexual characteristics. Testes specifically produce sperm and testosterone, which is crucial for male reproductive system development and secondary sexual characteristics.
