The generative nucleus divides mitotically to produce two sperm nuclei. One of those will fertilize the egg to produce the zygote, and the other will fuse with the two polar nuclei in the embryo sac to produce the endosperm in a process called "double fertilization".
Pollination
Pollination is the transfer of pollen from the male part of a plant (anther) to the female part (stigma), enabling fertilization and seed production to occur. This can happen through various mechanisms, such as wind, water, insects, birds, or animals carrying the pollen between plants. Once the pollen reaches the stigma, it travels down the style to fertilize the ovules in the ovary, ultimately leading to seed formation.
While still attached to the anther, the nucleus of the pollen grain divides, producing two nuclei, one of which becomes the tube nucleus, the other is called the generative nucleus. The generative nucleus divides again, forming two sperm cells. Once the pollen grain is released from the anther, it is transported (by wind or fauna) to the stigma of the female flower. Once a pollen grain has landed on the stigma, it begins to grow a pollen tube (there are three nuclei in the pollen tube, one from the tube nucleus, and the two sperm). When the pollen tube reaches the ovary, both sperm cells enter the ovule, one fuses with the egg nucleus, the other fuses with polar nuclei that is also inside the ovule, forming the endosperm.
Electrons are not part of the atomic nucleus.
In the ovule of a pineapple flower, there is typically one female nucleus, which is part of the embryo sac. This nucleus is involved in fertilization and eventually contributes to the development of the seed. Pineapples are classified as angiosperms, and their reproductive structures are adapted to facilitate the process of pollination and fertilization.
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
Pollination
Pollination. Fertilization is what occurs after pollination.
Pollination happens is when the pollen goes into the ovary.

When pollen falls on a flower's pistil, a process called pollination occurs. The pollen travels down the pistil to reach the ovary, where fertilization takes place. This fertilization leads to the formation of seeds, which eventually develop into fruits.

Cross pollination happens when the pollen of one flower is placed upon the stigma of another flower, whether of the same varietyor not.
