Question

Eggs are produced in
A. Ovary
B. Testis
C. Fallopian tube
D. Uterus

Answer 1

Hint: The reproductive system of sexually reproducing animals consists of: primary sex organs(called gonads) which produce gametes and hormones, secondary sex organs which participate in reproduction but not form gametes, accessory sex organs cause differences in the appearance of two sexes.

Complete answer:
The primary female reproductive organs, or gonads are the two ovaries. The ovaries are located in shallow depression, called ovarian fossa, one on each side of the uterus, in the lateral wall of the pelvic cavity.
The formation of female gamete i.e. eggs in the ovaries is termed oogenesis.
Oogenesis begins in females before they are even born, during early fetal development, primordial germ cells migrate from the yolk sac to the ovaries. Their germ cells differentiate within the ovaries into oogonia. Oogonia are diploid (2n) stem cells that divide mitotically to produce millions of germ cells. Oogonia finally divides mitotically and forms the primary oocyte, then the primary oocyte undergoes meiosis 1 and forms the secondary oocyte and first polar body.
This secondary oocyte is released from the ovary by the process called ovulation. This secondary oocyte completes meiosis 2 only after fertilization, and finally a mature egg formed along with the second polar body.

So the correct answer is A) Ovary.

Note:
Follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone have major roles in regulating the function of the female reproductive system. At puberty when the ovaries and uterus are mature enough to respond to hormonal stimulation, certain stimuli cause the hypothalamus to start secreting gonadotropin releasing hormone, this hormone stimulates the secretion of follicle-stimulating hormone and luteinizing hormone. These hormones in turn, affect the ovaries and uterus and the monthly cycles begin.
