• B. a phallic gland, b - vas deferens, c - small tubules, d - ejaculatory duct, e right phallomere
• C. a phallic gland, b - ejaculatory duct, c - vas deferens, d - right phallomere, e - small tubules
• D. a - small tubules, b - phallic gland, c - small tubules, d - ejaculatory duct, e testis
• E. a caudal style, b - phallic gland, c - small tubules, d - vas deferens, e - ejaculatory duct

Answer 1

Answer: (A)

a phallic gland, b small tubules, c vas deferens, d ejaculatory duct, e right phallomere

A. a phallic gland, b small tubules, c vas deferens, d ejaculatory duct, e right phallomere

EXPLANATION: This is a diagram of reproductive system of male cockroach. In the diagram 'a' is phallic gland, 'b' is small tubules, 'c' is vas deferens, 'd' is ejaculatory duct, 'e' is right phallomere. The duct of phallic gland opens near the gonopore. Male cockroach reproductive system has a mass of glandular tubules. The central tubules are called small short tubules. the vas deferens opens into ejaculatory duct through seminal vesicle. The another name of vas deferens is ductus deferens. Ejaculatory duct of male cockroach is mushroom-shaped. It is an elongated wide median duct. Phallomere is a chitinous asymmetrical structure. It acts as the external male genitalia. This genitalia surrounds the male gonopore.
