Detailed explanation-1: -The explosive pressure is generated as the seed pods dry out. A squirting cucumber is one example of a plant which uses this mechanism. Once the fruit of the squirting cucumber matures it explosively ejects the seeds.
Detailed explanation-2: -By bursting, the seeds of squirting cucumbers (Ecballium elaterium), violets (Viola pedata), and touch-me-not (Mimosa pudica) disperse. When the seeds burst, they travel a long way before coming to rest.
Detailed explanation-3: -Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.
Detailed explanation-4: -Seeds of plants like beans, peas, etc. are dispersed by explosion of their pods. They are thrown in different directions and they germinate there to grow into new plants.
Detailed explanation-5: -Jewelweed is an annual, meaning it lives only for one year and comes back from the seeds the next year. The seeds grow in pods, which expand in size, building up pressure – until they explode when touched. This is why they are also called touch-me-nots.
