2. Water
Plants which grow beside water often rely on water
to transport their seeds for them. They may
produce light seeds which float on water, or there
may be fluff on the seed that will help it float. It
also may have a fibrous husk, like in a coconut, to
help it float.
Examples:
Coconut
PongPong
Willow

3. Wind
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.
Examples:
Dandelion
Angsana
African Tulip

4. Force (Explosive)
All explosive fruits rely on the effect of
evaporation of water in the seedpod, so this
method of seed dispersal usually takes place in
the sun. An explosive fruit will
‘explode’, flinging its seeds far away from the
parent plant
Examples:
Rubber
Balsam
African Tulip

5. Animals
Animals eat the fruits that have fallen from the
trees and deposit the seeds in their droppings
several miles away.
Examples:
Berries
Date
Sunflower
