How does explosion help seed dispersal?

Ballistic or explosive seed dispersal is perhaps the most fascinating of seed dispersal mechanisms. 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.

Did you know facts about seed dispersal?

Dispersal by Wind Seeds can use wind to travel away from their parent plant. Some seeds, like those from an oak tree, can float on a breeze, much like we can catch a plane to Disney World. Depending on the strength of the breeze, the seeds can travel a decent distance away from their parent.

What type of seeds explode?

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.

Which plants seeds are dispersed by explosion?

Seed Dispersal by Explosions Okra, Lupins, gorse, and broom are a few examples of plants whose seeds are dispersed by Explosions. Pea and bean plants also have pods and the seeds burst out when they ripen and pod has dried.

What do you mean by seed explosion?

Explosive seed dispersal is an example of autochory, where seeds are dispersed by a plant’s own mechanisms, and is found in various angiosperm lineages including the genus Cardamine.

What is plant explosion?

When gas leaks come into contact with a source of heat, they begin to expand and can explode. If a chemical is released within a hazardous area, it can react with a heat source to cause a serious accident. Sometimes, plant explosions are caused by the use of impure chemicals.

Do seeds grow in poop?

Many tree species that produce fleshy fruits make use of seed dispersal through animal poo. ‘However, we should not neglect the fact that seeds of many plant species with dry fruits may survive animal digestive tracts and are dispersed in animal faeces,’ Si-Chong explains.

Do birds poop out seeds?

Through Droppings When eating fruit, birds digest the fleshy part and then pass the seeds out along with their droppings. The fecal material gives seeds a dose of fertilizer high in nitrogen, which can help fuel growth.

Which of the following seeds are disappeared by explosion?

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

Why seed dispersal is important?

Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
