NEET BIOLOGY

Detailed explanation-1: -Ovaries are the principal female reproductive organs located in the pelvis. They contain female gamete cells called oocytes or eggs. These ovaries contain fluid-filled structures known as follicles. It is in these follicles the eggs are enclosed.

Detailed explanation-2: -In the ovary, all eggs are initially enclosed in a single layer of cells known as a follicle, which supports the egg. During the follicular phase (first part of the menstrual cycle), one or two ovarian follicles grow due to the action of FSH. As the follicle grows it produces oestradiol.

Detailed explanation-3: -Ovules are attached to the placenta in the ovary through a stalk-like structure known as a funiculus (plural, funiculi).

Detailed explanation-4: -The female reproductive part of a flower is called pistil. It is divided into three parts: stigma, style and the ovary. The female sex cells or ovules are present in the ovary.

Detailed explanation-5: -Each ovule contains an egg. 1 Pollen grains land on the stigma and begin to grow pollen tubes. Sperm cells within the pollen grain move down the pollen tube and into an ovule. Fertilization occurs as one of the sperm cells fuses with the egg inside the ovule.
