Seed Dispersal Quiz – Seeds on the Move

Seed dispersal is how plants move their seeds away from the parent plant. Spreading out helps seedlings avoid competition for light, water and nutrients and lets plants colonize new places, from forest gaps to remote islands.

Plants use many methods. Wind carries dandelion parachutes and spinning maple seeds, water carries coconuts and lotus seeds, and animals spread seeds by eating fruit or carrying burrs on their fur. Some plants, such as balsams, fling seeds from bursting pods.

Seed dispersal shapes whole ecosystems. Jays and squirrels plant oak forests by burying acorns, ants carry seeds to their nests and fire opens the cones of some pines. Nature's designs have inspired inventions like Velcro and studies of flying seeds for drones.
