In flowering plants, egg cells are formed within the ovules located in the ovary of the flower's pistil, while sperm cells are produced in the pollen grains formed in the anthers of the stamen. During pollination, pollen grains transfer from the anthers to the stigma, where they germinate and form a pollen tube that grows down to the ovule. This process allows the sperm cells to travel through the pollen tube to fertilize the egg cell, resulting in the formation of a zygote and eventually a seed. Thus, the reproductive structures of flowers facilitate the formation of both egg and sperm cells for sexual reproduction.
embryo
first,in the embryo second,uterus
it will produced because of sexuality between man and woman..there are lot of spermcell who want to pass or go enter to the core which is the eggcell.

They met in the uterine tube of the woman. Once fertilized, the new embryo moves to the uterus.
COCKROACH
the act or prosses of intinting biological by incemanition
only one has to reach the egg to fertalize it
A large number of mitochondria power the flagella of sperm cells.
This varies greatly but generally between the ages of 10 and 50.
Technically speaking, the female's mother. When a woman is born, she already has all of her eggs that she will need already in her ovaries. Although she does not start releasing them until puberty.
An egg cell only needs one sperm cell to be fertilized. Human male ejaculate can contain 200 000 000 sperm.
