Cross pollination is a natural method in which transfer of pollen takes place from an anther of a flower of one plant to a stigma of a flower of another plant of the same species. Preparation and fertilization can moreover be refined by cross-fertilization. Animals are crucial for the reproduction of plants, and they support the spread of seeds. The mechanism of cross-pollination allows all unisexual plants to reproduce. Cross-pollinating can result in more viable and healthier plants because it combines two diverse gene pools. Artificial pollination is a method used by horticulturists to manually transfer pollen from one plant to another, triggering fertilization.
