Fertilization in floral plants.. The nucleus of the female genital nucleus in the pollen grain with the female nucleus in the egg

Fertilization in floral plants:
Definition: is the union of the male genital nucleus in the pollen grain with the female nucleus in the egg.
Fertilization Process:
1 - the grain of the vaccine on Almsim absorbs the solution of diabetes secreted from Almsem inflated and out of the tube of the vaccine and the direction of the nucleus of the vegetative and followed by the reproductive nucleus, which is divided into two male reproductive nuclei.
2. The vaccine tube breaks the tissue of the mesum, pen and ovary until it reaches the egg through the opening hole.
The embryo of the vaccine enters the embryonic sac and the vegetative nucleus disappears. A double fertilization occurs where one of the male nuclei binds together in the female nucleus. The zygote (the seed embryo) is later formed and the other combines with the polar nuclei. The endosperm nucleus produces the endosperm in the seed later.
