It varies somewhat but it works out to be, on average, about every 28 days. There is variation between women and even from cycle to cycle for individual women. In girls just starting menstruation and women undergoing menopause it can be (and usually is) much more irregular.
Note: the average is for the release of ONE egg and there are TWO ovaries.
ovum
mature ovary forms the pistil
I you and I are thinking of the same thing, it's not a cell. But it's called the ovary.
Flowers don't mature into anything. The ovary matures into the fruit when (and if) the flower is pollinated and the ovules fertilised. The fertilised ovules become the seed and the ovary becomes the fruit.
A mature ripened ovary of a plant is called a fruit. It develops from the ovary after pollination and fertilization, typically containing seeds. Some examples of fruits are apples, oranges, and tomatoes.

Oviduct is where the egg cells are fertilized while the ovary is where the egg cells are produced and where they mature.

Yes. Eggs mature in follicles in the ovaries. Just before ovulation occurs, the follicle that contains the maturing egg rises towards the surface of the ovary. Ovulation occurs when the follicle and the ovarian surface open allowing the egg to drift out of the ovary.
