Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (male gametes) to the plant carpel, the structure that contains the ovule (female gamete).

application of male pollen to the female stigma, or ovule, of a plant

Pollination
The transfer of pollen from the anther to the female stigma is termed pollination. This is accomplished by a variety of methods. Entomophyly is the transfer of pollen by an insect. Anemophyly is the transfer of pollen by wind.
Pollination
When a pollen grain reaches the stigma, it germinates into a pollen tube. The germ cell divides by mitosis forming 2 sperm cells.
pollination -- Process of transferring the pollen from its place of production to the place where the egg cell is produced. This may be accomplished by the use of wind, water, insects, birds, bats, or other means.
pollination The transfer of pollen from the anthers to the stigma by a pollinating agent such as wind, insects, birds, bats, or in a few cases the opening of the flower itself.
self-pollination
The transfer of pollen from anther to stigma in the same flower or to another flower of the same plant, leading to self-fertilization.

Pollination
Transfer of pollen from the anther to the stigma in angiosperms or from the microsporangium to the micropyle in gymnosperms.
pollination The transfer of pollen to a receptive surface; the stigma in angiosperms or the pollination droplet in most gymnosperms.

Autogamy
Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone).
Cross-pollination. Fertilization of a plant from a plant with a different genetic makeup. Crossing-over. The exchange of DNA sequences between chromatids of homologous chromosomes during meiosis. Culture.
Hybrid: Seed or plants produced as the result of controlled cross-pollination as opposed to seed produced as the result of natural pollination. Hybrid seeds are selected to have higher quality traits (for example, yield or pest tolerance).
Some of these species may be beneficial, such as those that provide pollination or consume pests. Laboratory experiments suggest an increased mortality of Monarch butterflies that ingested Bt corn pollen.
By cross pollinating the pea plants, he carefully controlled which plants reproduced, and tracked how each of these traits was passed on from generation to generation. Cross pollination means that Gregor Mendel took pollination from a pea plant ...

It is a plant model system of choice because of the additional advantages of short generation time (about five weeks), high seed production (up to 40,000 seeds per plant) and natural self-pollination ...
That variety is often dependent on what kind of creature helps out with the pollination. If I am a big insect, I will be looking at plants with big flowers. If I am a tiny little bug, I might live my whole life inside a flower.

Although genetically modified plants can decrease the use of pesticides and herbicides and thereby benefit the environment, a concern is that plants engineered to be more resistant to herbicides may pass on that trait through cross-pollination to ...
