Seed Dispersal

Wind

• The wind carries the spore or seed.
• Wind can carry the seeds for miles.
• The wind helps the seed or spore to travel to a different area.
• Some tall trees produce seeds with stiff wings covering the seed that enable them to fly long distances. The wings are twisted and balanced so that the seed spins around as it is carried along by the wind. These natural adaptations for using the wind to transport the weight of the seed must be technically accurate, as the wings of modern planes and helicopters are designed in the same way.

Drop and Roll

• The seed gets bigger and it pops open and the seed roles to a different area.
• The casing of the fruit from trees such as horse chestnuts (conkers) split when they land on the ground.The fruit then rolls away from the tree
• The seed could travel for miles if their is wind.

Water

• The seed falls down to water and the water. carries it to a different area.
• Some fruits are waterproof and can float. Coconuts are a good example.
• Some seeds have woody, waterproof coverings which enable them to float in the salty water for long time.

Animals

• A animal eats the seed and they poop the seed out.
• The seeds that cling to the animal's fur are called Hitchhiker seeds.
• In the deserts of North Africa, elephants eat the fruits that have fallen from the trees and deposit the seeds in their droppings several miles away.

Seed Dispersal Conclusion

• Wind can carry the seeds for miles.
• The seed gets bigger and it pops open and the seed roles to a different area.
• The seed falls down to water and the water. carries it to a different area.
• The seeds that cling to the animal's fur are called Hitchhiker seeds.
