Question

Choose the correct option for the path of movement of sperms in cockroach.

• A. Testis$\to$seminal vesicle$\to$Male gonopore$\to$ejaculatory duct
• B. Testus$\to$ejaculatory duet$\to$vasdeferens$\to$Male gonopore
• C. Vasdeferens$\to$seminal vesicle$\to$ejaculatory duct$\to$male gonopore
• D. Testic$\to$seminal vesicle$\to$vasdeferens$\to$male gonopore

Answer 1

The correct option is C Vasdeferens$\to$seminal vesicle$\to$ejaculatory duct$\to$male gonopore

In a male cockroach, a pair of testes is present one on each lateral side of abdominal segments 4 to 6. From each testis, a thin vas deference arises which then opens into the ejaculatory duct through seminal vesicle. The ejaculatory duct opens into male gonopore present at the ventral side of anus.
Thus the correct path that sperms take is:
Testis$\to$vas deferens$\to$seminal vesicle$\to$ejaculatory duct$\to$male gonopore
