Hemerochory

Hemerochory is when seeds travel from one place to another with the help of water. Think about a little seed that wants to move to a different spot to grow into a big plant. Instead of walking or flying, the seed takes a ride on the water. This is like when you play in a pool and try to catch little toys floating around.

In the same way, when it rains, some seeds fall into the flowing water and then they travel with the water. They might end up in a new place where they can grow and become a beautiful plant. This is like when you put a boat in the river and it goes downstream. The seed is like the boat and the water is like the river.

This way of traveling is very helpful for some plants that don't want to stay in the same place forever. Some plants have seeds that can float for a really long time, even in the ocean, and eventually reach a new home. Hemerochory helps these plants to spread out and grow in different places.
