Question

Choose the incorrect list pertaining to male reproductive system of a cockroach from the following:

• A. Testes, seminal vesicle, male gonopore, accessory glands, gonapophysis
• B. Testes, seminal vesicle, male gonopore, mushroom gland, vas deferens
• C. Testes, seminal vesicle, male gonopore, collateral glands, spermatheca
• D. Testes, seminal vesicle, male gonopore, phallic gland, phallomeres

Answer 1

The correct option is C Testes, seminal vesicle, male gonopore, collateral glands, spermatheca

The parts of the male reproductive system of a cockroach are testes, seminal vesicle, male gonopore, accessory glands, vas deferens, ejaculatory duct and gonapophysis/phallomeres. Accessory glands contain mushroom gland (helps in nourishing sperms) and phallic gland (helps in the formation of spermatophores).

The collateral glands and spermatheca are parts of the female reproductive system of a cockroach. The collateral glands help in the formation and hardening of egg case or ootheca whereas the spermatheca stores sperms received during copulation.
