After fruits such as grapes and persimmons are eaten by birds or beasts, the seeds will be excreted along with the feces and play a role of transmission. As soon as the fruit or seed of some plants touches it, it hangs firmly on animal fur or human clothing and is spread to a distance, such as Xanthium sibiricum, Bidens bipinnata and so on. Birds can help spread the seeds. The birds swallow the seeds into their stomachs, then they are excreted by bird droppings, and the seeds can be spread to new places.

When the fruit of the water lily is ripe, it sinks to the bottom of the water. After the pericarp is rotten, the seed with a spongy outer seed coat will float and float to other places.
