“Self-pollination” means that the pollen on the stamens of the same flower pollinates the pistils. Some plants can also produce fruits in this way, but some plants are self-pollinating. Pollination is sterile. Pollen must be obtained from another flower of the same plant, or even pollen from another same plant (completed by wind or insects) to produce fruit. This is called "cross-pollination" or "Cross-pollination".
