Answer:
cross pollination
Step-by-step explanation:
plants dont want self pollination. Self pollination is taking pollen from one flower of a plant to another flower of the same plant (plants can have multiple flowers). Plants don't want this because they want to widen the gene pool meaning they want to reproduce with other plants of the same species. Cross pollination fits this description. Cross pollination is taking pollen from one flower to another plant from the same species's flower. Plants dont want to reproduce with themselves, they want to reproduce with other plants from the same species. Cross pollination is the best way to do that
