Which plants disperse their seeds through explosion?

Which plants disperse their seeds through explosion?

Pea and bean are two plants whose seeds are dispersed by explosion of their fruits.

What causes the explosion for the explosive dispersal of seeds?

During explosive seed dispersal, the fruit walls of the C. hirsuta fruit pod coil rapidly, transferring kinetic energy to the seeds to fire them away (Figure 1b). Coiling is a consequence of the bi-layer configuration of the fruit wall (Figure 1b).

Which seeds that scatter by bursting?

By bursting, the seeds of squirting cucumbers (Ecballium elaterium), violets (Viola pedata), and touch-me-not (Mimosa pudica) disperse.

Which of the following spreads by bursting of the pods?

Pea and beans are plants that disperse their seeds by ‘bursting’. EXPLANATION: The plants keep the seeds in the pods and when the pods dry, they burst open to disperse their seeds.

What is bursting of seed?

The bursting of seeds are triggered by many environmental factors such as wind, rain and physical contact with an animal. If an animal triggers the seeds to burst, it may stick to the animal, enabling seed germination far away from the parent plant.

How are seeds dispersed by explosive dispersal?

This is explosive dispersal. 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. Click to see full answer. Similarly, how are the seeds dispersed by explosion? Dispersal by Explosion.

What is ballistic seed dispersal and how does it work?

Ballistic seed dispersal is one of the most stunning ways that plants manage to scatter their seeds without external help. Although no explosive substances are really involved in this process, it’s still enjoyable to watch when the seed pods of plants start to pop up and launch their seeds in every direction.

Do plants explode when ripe?

Some plants have pods that explode when ripe and shoot out the seeds. Lupins, gorse and broom scatter their seeds in this way. When the seeds are ripe and the pod has dried, the pod bursts open and the peas and beans are scattered. how do plants explode? When gas leaks come into contact with a source of heat, they begin to expand and can explode.

What is it called when seeds are dispersed by wind?

This is wind dispersal. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.
