Cross-pollination is the process by which pollen from one flower fertilizes the ovule of another flower, leading to the production of seeds. This method is essential for many plants, as it promotes genetic diversity, which can enhance resilience and adaptability. Cross-pollination often occurs with the help of pollinators like bees, butterflies, and birds, which transfer pollen while feeding on nectar. In agriculture, cross-pollination is utilized to create hybrid plants that may have improved traits, such as higher yields or disease resistance. Farmers often encourage cross-pollination by planting different varieties of the same crop nearby, ensuring that pollinators can easily move between them.
