Gametes are the mature sperm and egg cells. The ovary contains partially developed egg cells and each month one or more complete their development. Human ovaries produce all the immature eggs prior to birth of the female.
In the testicles of males there is a population of sperm stem cells that are able to divide, producing a cell that can complete development (more mitosis and then meiosis) and a cell that remains as a stem cell (capable of dividing again and again).

∙ 13y agoDepends on organism. If you mean human, you have to go to embryonal level. A new embryo of future female contains primordial germinal cells which divide into many future eggs (oocytes, female gametes). So already before birth, new female has all the oocytes. Since puberty, in ovary (ovarium), one oocyte per month undergo maturation, it grows and evolves into mature oocyte which is able to form zygote when fertilized by spermatozoon.

What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
What is the difference between antheridia and archegonia?
Antheridium is the male part of seedless plants, like algae and fungi, and the archegonium is the female part.
Gametes are reproductive cells with nuclei resulting from?
They are generated from cells that underwent meiosis.
What is the female organ that produces sex cells?
The female organ that produces sex cells is called the ovary, and produces ova.
How does Irish moss reproduce?
Chondrus crispus( Irish moss) undergoes an alternation of generation life cycle common in many species of algae . There are two distinct stages: the sexual haploid gametophyte stage and the asexual diploid sporophyte stage. In addition there is a third stage- the carposporophyte, which is formed on the female gametophyte after fertilization. The male and female gametophytes produce gametes which fuse to form a diploid carposporophyte, which forms carpospores, which develops into the sporophyte. The sporophyte then undergoes meiosis to produce haploid tetraspores (which can be male or female) that develop into gametophytes. The three stages (male, female and sporophyte) are difficult to distinguish when they are not fertile; however, the gametophytes often show a blue iridescence
Flower structure containing one or more ovules?
The flower structure that contains one or more ovules from which female gametophytes are produced is an ovary. Carpels is the innermost part of a flower that produce the female gametophytes.
What structure does the male gametophyte become?
In flowering plants, megaspores become the female gametophytes.
Are the male and female gametophytes separate plants or part of the same plant?
Male and Female gametophytes are in separate plants
Female spores that eventually become female gametophytes in conifers?
megaspores
Which female structure produces the eggs?
Fallopian tube
In seed plants what do female gametophytes produce?
egg
What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
What produces eggs and sperm cells during the life cycle of a plant?
gametophytes
Where are the female gametophytes produced in non vascular plants?
antheridium
What advantage do gametophytes that are either male or female have over gametophytes with both male and female structures?
The gametophyte will not fertilize its own egg.This increase the chance of offsprings will have new combination of genes
What flowering plants becomes the female gametophyte?
In flowering plants, megaspores become the female gametophytes.
What does an archegonium produce?
the archegonium structure produces haploid egg cells (the female reproductive structure-think "egg" like archEGonium) wheras the antheridium produces haploid sperm cells (the male reproductive structure)
