Explosive action:
The side of the seedpod facing the sun dries out more quickly than the side in the shade, causing the pod to buckle and pop open. The seedpods then curl up like animal horns, sending the seeds flying.]]> 2017-02-01 10:31:26 UTC https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150782415 Shawn Lim https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150801537   Fruits with edible seeds that are dispersed by animals are usually fleshy and sweet with small hard seeds. Examples are: Guavas and raspberries.
  Fruits that cannot be eaten are discarded. Examples are: Mango and durians.
Fruits that have hooks or stiff hair cling onto passing animals. They can be carried for a long distance before they drop off or are brushed off. Examples are: Mimosa, Cleaver, Love grass ]]> 2017-02-01 12:22:17 UTC https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150801537 Kendrick https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150805167 Fruit that are powerful enough to burst their seeds out far away]]> 2017-02-01 12:42:39 UTC https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150805167 Tricia Sim https://padlet.com/mrs_jessy_low1/xghcezcnwgs9/wish/150810494 When there is sunlight, the seed pod will dry up and burst, causing the seeds inside to fly at different directions.

Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. This is explosive dispersal. An example of this is plants which belong to the Pea Family (Leguminosae). They produce seed pods which dry in the sun.

As a pod dries, tensions are set up in the wall of the pod eventually causing it to split along two lines of weakness. As the two halves curl back, suddenly released like a tense spring, they flick out the seeds inside in an explosive manner. In the picture opposite, the halves of a seed pod which has ruptured in this way are clearly twisted, in contrast to the whole pod which is entire.

Gorse is a good example of this. Sitting near Gorse bushes on a hot day in summer in Britain, can be like sitting near a firing range, as the exploding pods sound almost like gun shots. The small seeds are very effectively thrown away from the immediate area.

 Lupins, gorse and broom scatter their seeds in this way.

Pea and bean plants also keep their seeds in a pod. When the seeds are ripe and the pod has dried, the pod bursts open and the peas and beans are scattered.
