fertilization
double fertilization
Pistil
Fetilization. Results in a zygote.
Fetilization in plants occurs in the ovary; here the male sperm (from the pollen grain) fuses with the ovule
In humans?,, A female human is borned with all the eggs she will ever have.
They form from the merger of two haploid (half-gened cells: a sperm and an egg). Actually in mammals the egg swallows the sperm, and the nuclear material fuses together.
Sperm do not go up the wrong ovary. During fertilization, sperm typically swim through the cervix, uterus, and into the fallopian tubes where one of the ovaries releases an egg. The sperm then have the opportunity to fertilize the egg in the fallopian tube, not the ovary itself.

It get fused with nucleus of ovum.That process is called Fertilization.
When sperm fuses with egg it is called fertilization .
When sperm fuses with egg it is called fertilization .
In humans?,, A female human is borned with all the eggs she will ever have.
After pollination, fertilisation takes place. 1. In plants it is a double fertilisation in which two sperm cells fertilize cells in the plant ovary. 2. The process begins when a pollen grain sticks to the stigma of the pistil which germinates, and grows a long pollentube. This cell divides by mitosis into two haploid sperm cells. 3. As the pollen tube grows, it makes its way from the stigma, down the style and into the ovary. One sperm makes its way to fertilize the egg cell, producing a diploid (2n) zygote. The second sperm cell fuses with two cell nuclei, producing a triploid (3n) cell. 4. The ovary develops into a fruit and the ovule develops into seed.
They form from the merger of two haploid (half-gened cells: a sperm and an egg). Actually in mammals the egg swallows the sperm, and the nuclear material fuses together.
ovary
The chronological stages in the human fertilization process begins when an egg is released from the ovary. It becomes fertilized by sperm and then implants in the uterus.
a zygote is form when an egg and sperm fuses togerther .
