Question

Primary sex organ are
A. Ovary/ testis
B. Uterus/ seminal vesicles
C. Breast/ Beard
D. Spermatic cord

Answer 1

Hint: Ovaries, testis and gonads are the primary sex organs of the reproductive part of the body. The reproductive organs help with secretion in the egg, sperm and hormones. The primary male sex hormones are testes that’s responsible for making testosterone and ovaries are the primary organs of female that are located in a pair in the abdomen.

Complete answer:
Sexual reproduction part of the body in which reproductive organs are present such as ovary and testis. Primary sex organs denotes the capacity of the reproductive glands gonad to produce either eggs or sperm in the reproductive system. The primary sex is female if eggs are produced the reproductive glands, and if sperm are produced the reproductive system is testis and primary sex is male.
Hermaphroditic is a condition obtained if the gland produces both sperm and eggs simultaneously. The nature of the gonads depends upon the hermaphrodite primary condition in the male and female. The fertilization of the eggs of females when the male delivers sperm cells in enormous numbers in the right place of the reproductive system of the female. Full advantage of double parentage is obtained in the case of hermaphrodite organisms various devices are employed to ensure cross pollination and also cross fertilization because of this reason the reproductive cells of different parentage come together and fuse in pairs.

Therefore the correct option is (A).

Note: The division of labour use to distinguish between the complementarity of both male and female sex cells. It’s nucleus together with the large mass of cell substances for development and growth of the fertilization and present cells are without any capacity for independence. On the other side male cells are motile cells capable of swimming through liquid, seawater body fluid also contributes nucleus but little process in the fertilization.
