Question

In male cockroaches, sperms are stored in which part of the reproductive system
  1. Testes
  2. Vas deferens
  3. Seminal vesicles
  4. Mushroom glands


Solution

The correct option is C Seminal vesicles
The male reproductive system has two testes and they produce the sperm. From each testis rise a thin tube called as Vas deferens. Two vasa deferentia from either side run posteriorly and open into the ejaculatory duct through a seminal vesicle. Ejaculatory duct opens into a male gonopore situated below the anus. There is a mushroom shaped accessory reproductive gland is present near the 6 and 7th segments. Secretions of this gland nourish the sperm and help in the formation of spermatophore formation. Male gonapophysis or phallomeres represent the external genitalia. Sperms are stored in seminal vesicles and form spermatophores which are discharged during copulation.
