Question

Which of the following male and female structures are least alike in function?

• A. Seminiferous tubule-vagina
• B. Testes-ovaries
• C. Spermatogonia-oogonia
• D. Vas deferens-oviduct

Answer 1

The correct option is A Seminiferous tubule-vagina

Seminiferous tubules are located within the testes and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa. The epithelium of the tubule consists of a type of sustentacular cells known as Sertoli cells, which are tall, columnar type cells that line the tubule. The vagina is a muscular canal lined with nerves and mucous membranes. It connects the uterus and cervix to the outside of the body, allowing for menstruation, intercourse, and childbirth.

So the correct option is 'seminiferous tubule-vagina'.
