Cross-pollination is the process where pollen from one flower fertilizes the ovule of another flower, leading to the production of seeds. This method often occurs with the help of insects, birds, or wind, which transfer pollen between different plants. Cross-pollination promotes genetic diversity, making plants more resilient to diseases and environmental changes. Many flowering plants, including fruits like apples and vegetables like cucumbers, benefit from cross-pollination. This process can enhance the quality and yield of crops, as it often results in stronger and more productive plants. Farmers and gardeners may encourage cross-pollination to improve their harvests.
