Seed dispersal syndrome is like a game that plants play to spread their seeds far away from them. Just like how you throw a ball to your friend to play catch, plants have different ways to spread their seeds.
Some plants have seeds that are very light and fluffy, like feathers. When the wind blows, these seeds can be carried on the wind and scattered far away from the parent plant. Other plants use animals to help them spread their seeds.
For example, some plants make seeds that are yummy and tasty for animals to eat, like fruits. When the animals eat the fruits, they also eat the seeds inside. Later, when the animals poop, the seeds come out with their poop and can grow into new plants far away.
Other plants have seeds that are very sticky and can stick to an animal's fur. As the animal moves around, these seeds will fall off and can grow into new plants.
Each plant has its own special way of spreading its seeds. By doing this, they can make sure that their babies grow up in new places and have a better chance of survival.
