Plants cannot walk, but their seeds can travel. Moving seeds away from the parent plant is called seed dispersal. It helps new plants find their own light, water and space, so they do not compete with the parent, and it lets plants spread to new places.
Wind: light seeds with wings or fluffy parachutes, such as maple seeds and dandelions, are carried by the wind.
Animals: juicy fruits are eaten and the seeds are dropped in the animal's droppings. Seeds with hooks, such as burrs, catch on fur and clothes. Some animals bury nuts and forget them.
Water: seeds that float, such as coconuts, are carried by rivers and the sea.
Bursting: some pods dry out and split open suddenly, flinging their seeds away — pea and bean pods are examples.
