Question

Select the correct route for the passage of sperms in male frogs.

• A. Testes→ Bidder’s canal→ Kidney→ Vasa efferentia→ Urinogenital duct→ Cloaca
• B. Testes→ Vasa efferentia→ Kidney→ Seminal Vesicle→ Urinogenital duct→ Cloaca
• C. Testes→ Vasa efferentia→ Bidder’s canal→ Ureter→ Cloaca
• D. Testes→ Vasa efferentia→ Kidney → Bidder’s canal→ Urinogenital duct→ Cloaca

Answer 1

The correct option is D

Testes→ Vasa efferentia→ Kidney → Bidder’s canal→ Urinogenital duct→ Cloaca

The correct option is D.

Explanation of the correct option:

1. Sperm are produced in the frog's testes.
2. The mature sperms are transported from the testes into the vasa efferentia.
3. The vasa efferentia enters the kidneys after passing through the mesorchium.
4. As a result, the sperm enters the kidney.
5. Sperms enter the Bidder's canal from the kidney.
6. They then enter the urinogenital duct and exit through the cloaca into the water.
7. The sperms fertilise the eggs released in water by the female frog.

Final answer: The correct route for the passage of sperms in male frogs is Testes→ Vasa efferentia→ Kidney → Bidder’s canal→ Urinogenital duct→ Cloaca.
