Question

_______ is the primary reproductive organ in females.
A.Ovary
B.Testes
C.Uterus
D.Vagina

Answer 1

Humans reproduce by sexual reproduction and it includes several steps. Gametogenesis is the name of the process by which gametes are formed in male and female reproductive organs respectively.

Complete step by step answer: We know that steps in human reproduction include gametogenesis, insemination, fertilization, cleavage, implantation, gestation, and parturition.
In the process of gametogenesis, male gamete is formed in male reproductive organs that include a pair of testes, accessory ducts, accessory glands, and external genitalia.
Female reproductive organs include a pair of ovaries, a pair of oviducts or fallopian tubes, uterus, cervix, vagina, external genitalia, and the mammary glands.
We know that the primary female reproductive organ is the ovary. They are seen in pair in females and it produces the oogonia.
Testes is an oval structure and seen in the scrotal sac. It is seen as pairs. Each testis is composed of several testicular lobules upto 250 in number.
The uterus is a single organ that is seen as attached to the pelvic wall with the help of ligaments. Note that shape of uterus is like that of an inverted pear. The narrow portion of uterus is called cervix. Cervical canal along with the vagina forms the birth canal.
Mammary glands are also part of the reproductive system as milk production for the young ones takes place in the mammary glands after parturition.
Vagina is actually a small tube that extends from the vulva to the cervix. Female external genitalia is made up of mons pubis, labia majora, labia minora, hymen, and clitoris.
Hence the correct option is A.

Note: Primary reproductive organ in males are testes. Seminiferous tubules present in testicular lobules contain several male germ cells and Sertoli cells. Male germ cells undergo meiosis division that finally leads to sperm formation.
