Choose the accurate route for the passage of sperm in the male frog:
Testes → Vasa efferentia → Kidney →Seminal vesicle →Urinogenital duct → Cloaca
Testes → Vasa efferentia → Bidder's canal → Ureter → Cloaca
Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca
Testes → Bidder's canal → Kidney → Vasa efferentia → Urinogenital duct → Cloaca
Answers (1)
Option 3 is the correct answer that is,
Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca
In male frogs, the sperm follows a specific route during its passage for reproduction. The process starts with the sperm being produced in the testes. From there, they travel through the vasa efferentia, which are tiny ducts that connect the testes to the kidney.
Once in the kidney, the sperm moves into the Bidder's canal, a specialized structure found in certain species of frogs. From the Bidder's canal, the sperm then enters the urinogenital duct, which is responsible for carrying both urine and reproductive fluids.
Finally, the sperm reaches its destination, the cloaca. The cloaca is a common chamber where both reproductive and excretory systems meet. In the cloaca, the sperm can be released during mating to fertilize the eggs.
Hence, the correct answer is option 3.
