Resumen:
Pollination is the transfer of pollen grains, which contain male gametes, to the receptive part of the ovulebearing organ of seed plants (the mycropyle in Gymnosperms and the stigma in Angiosperms). Pollination, a crucial step in sexual reproduction of seed plants, can occur through abiotic vectors (wind, water) and biotic vectors (insects, birds, other vertebrates). Introduced species may influence pollination either directly, when the alien is a plant or a pollinator, or indirectly, when the alien is another kind of species that influences the pollination process by affecting the plant, the pollinator or both. In addition, pollination can modulate the establishment and spread of introduced plant species
