Plants disperse their seeds in various ways to ensure their propagation and survival. Some common methods of seed dispersal include wind dispersal, where seeds are carried by the wind to new locations, water dispersal, where seeds float on water to reach new areas, animal dispersal, where seeds are eaten by animals and then excreted in a new location, and self-dispersal, where seeds are ejected from the plant due to internal pressure or mechanical means. Each method has evolved to help plants colonize new areas and increase their chances of germination and growth.
