Pollen is scattered by the wind or by animals.
animal dispersal and wind dispersal
Pollen can be scattered by wind, or by pollinating insects such as bees.
Pollen grains with generative and tube nuclei have two haploid nuclei.
Pollen grains are formed within the anthers of flowering plants, which are the male reproductive structures where pollen grains develop and mature. The process of pollen grain formation is called microsporogenesis.
It depends. If the pollen that the plat came from is part of the other plant's family, then it is crossbred. However, if not, the pollen will not travel down through the other plant's stigma. Such as a white and red rose will make either a pink or a red rose.

they produce a tiny tube that the pollen grains travel to the egg cell.
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.

By sending their male gametes to the female gametes through their pollen tubes after germination of pollen grains.
Using the higher magnification objective lens will enable you to observe a larger number of pollen grains, but they will appear larger and more detailed due to the increased magnification. Conversely, using the lower magnification lens will allow you to see fewer pollen grains in the field of view, but they will appear smaller and less detailed.
Yes because pollen grains form on the tip of the anther.
as many that stick to the stamen. it differs from plant to plant and it also depends on how many pollen grains stick to the insect that carries it. though once the pollen grain comes into contact with the stamen a pollen tube is created to reach the ovary. then two "sperm" come from this tube and one fertalizes the egg and one become the endosperm for nutrients for the egg/seed

Pollen grains are formed after meiosis in microspore mother cells. Neww genetic combinations are formed by crossing over which are carried to the pollen grains. The male plant has some advantageous genes in the pollen grains. Likewise gametogenesis in the ovule also takes place creating new combinations in the egg cell. When cross pollination occurs, this leads to broader genetic spectrum from two parents. Thus, the hybrid embryo produced in such seeds has more vigour due to increased heterozygocity.
