Pollination
Fertilization occurs when pollen joins with the ovule, resulting in the formation of a fertilized egg or zygote.
pollen joins an ovule to make seeds
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.
Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.
If The Pollen Tube Joins The Ovules They Will Have Fertilization And At The End After The Ovules Will Become The Seeds It Is One Or Many Seeds

Yes, pollen grains have a nucleus. The nucleus contains the genetic information necessary for the pollen to fertilize a plant's ovule.
The joining of the male nucleus from the pollen grain with the egg cell in the ovule is called fertilization. This process results in the formation of a zygote, which eventually develops into an embryo within the seed.
When viable and compatible pollen grains are brought in the vicinity of ovule having mature embryosac, gametic union will take place. This is called fertilization.
The fusion of pollen and ovule is called fertilization. This process involves the union of the sperm cell from the pollen with the egg cell in the ovule, resulting in the formation of a zygote, which eventually develops into a seed.
Pollen grains contain the male gametes required for sexual reproduction of a plant/ flower. These are haploid, and only contain half the full set of chromosomes; the other half is contributed by the female gamete (or ovule).A grain of pollen contains:a larger vegetative cell (also called the tube cell) inside of which is aa smaller germ cell (also called the generative cell).The pollen grain "germinates" on the stigma of the receptive flower and grows down the style, once it reaches the ovule the germ cell/ nucleus fuses with the nucleus of the ovule and an embryo is formed
The structure grown by a pollen grain that contains two sperm nuclei is called the pollen tube. The pollen tube is responsible for delivering the sperm nuclei to the ovule for fertilization in plants.
