How do exploding seeds dispersed?
Exploding plants disperse their seeds with high pressure bursts. Violets, poisonous squirting cucumbers, and touch-me-nots or Impatiens capensis (not to be confused with these touch-me-nots) have an effective way of dispersing their seeds: They burst! The forceful ejection sends the seeds flying as far away as possible from the original plant.

How do plants disperse seeds?
Some plants disperse their seeds forcefully by ejecting them. Sometimes the tension is so great, seeds may be ejected up to 200 feet away from the mother plant. This method of seed dispersal is called "ballistichory," a label that hints at the projectile-like emergence of seeds from their pods or capsules. This type of seed dispersal occurs because the fibers in the dried fruit pull against each other to create tension, and when the tension is great enough, the fruit splits open and the walls of the fruit spring back, flinging the seeds out with force.
What plant shoots seeds?
Some plants in the mallow family (Malvaceae) disperse seeds via ballistichory. The common garden vegetable okra (Abelmoschus spp.) is a plant that shoots seeds when touched, projecting its seeds several feet. Okras are annuals that are hardy in USDA zones 4 through 11. The kapok tree (Ceiba pentandra, also known as cotton tree) is native to South America and produces cream-colored flowers with an unpleasant smell. The pods burst open, sending both seeds and the exploding seed pod's cottony insulation into the wind. Kapok trees are hardy in USDA zones 10 through 11.

How does the length of a stalk affect the survival of a plant?
The length of the stalk casts the seeds far enough away from the parent plant to give them a fighting chance. The sheer number of seeds produced also helps their rate of survival .
Why is it important for seeds to travel away from the parent plant?
If all the seeds grew close to each other, they would have to compete for space, sun, water, and nutrients—and eventually die from overcrowding. Nature has developed mechanisms to avoid this.

How do plants disperse their seeds?
Plants disperse their seeds in lots of different ways. Some seeds are transported by the wind and are shaped to float, glide or spin through the air. Plants growing near a river may use the flowing water to transport their seeds. Some seed pods are designed to explode and throw the seeds a good distance from the parent plant.
Why do plants have seed pods?
Some seed pods are designed to explode and throw the seeds a good distance from the parent plant. Many plants also use animals to carry their seeds. This type of seed may have handy hooks which attach to an animal’s fur. Alternatively, the plants might make tasty fruit to enclose the seeds, which attract animals to eat them.
How far do fruit seeds explode?

The acidic juices in the digestive tract cause the seed to undergo scarification, ...
Why do milkweed pods have yellow flowers?
The clusters of successful yellow flowers attest to the effectiveness of wind dispersal, even for a weed. Cottonwood fluff and the silky insides of Milkweed pods also ride the wind. Milkweed’s horn-shaped pods open up when the seeds are mature, and float on soft, silky material that looks like flossy threads.
What happens to the seeds of Jewel Weed?

Why is it important for plants to spread out seeds?
Plant are fixed to the ground and cannot move from one place to another. If all seeds fall and germinate near the plant, they will not get enough sunlight, Water and space to grow. So, it is important that the seeds are spread out. Nature helps the seeds to travel away from the parent plant. This process of scattering of seeds is called seed dispersal.
How do ants pick up seeds?
In Australia, where most of the plants sold and grown in Europe as Mimosa, are from, there are ants which pick up the seeds by the piece attached which is called an elaiosome. This is nutrititious. The ants carry them to their burrows, take away the elaiosome for eating, and discard rhe seed, often underground. The seed can lie in wait for a good soaking for may take many decades. Then it can sprout and grow up far from its parent tree or shrub. In fact it seems this strategy is used by many plants in related genera too right across

How do plants reproduce?
Plants have different reproductive manners. For instance, flowering plants rely on insects to harvest pollen. One bee will travel to many different flowers in one day. When the bee collects the pollen in the flower from the stamen, it gets some of the pollen on it 's body and legs; this pollen will be transferred to the next flower it visits, as the bee must pass by the pistil.
