Question

Select the correct statements regarding ovaries.
I. Ovaries produce the female gamete.
II. Ovaries produce the hormone that regulates the development of secondary sexual characters.
III. FSH is produced by the ovary.

• A. I and II
• B. I and III
• C. II and III
• D. I, II and III

Answer 1

The correct option is A I and II

At puberty when the ovary and uterus are mature enough for hormone stimulation, the hypothalamus starts releasing the gonadotropin releasing hormone.

Gonadotropin releasing hormone (GnRH) is secreted by the hypothalamus which stimulates the anterior lobe of the pituitary gland to secrete luteinising hormone (LH) and follicle stimulating hormone (FSH).

FSH acts on the ovary and stimulates the growth of the ovarian follicles and formation of estrogen hormones.

Estrogen promotes the development of secondary sexual characters in females like development of mammary glands, high pitch voice etc.

The female gamete is produced inside the ovarian follicles under the influence of hormones.

Hence the statements I and II are correct.
