Most of us know that humans and animals reproduce sexually. Dispersal by Explosion. • It prevents overcrowding of plants • It reduces competition among fruits and seeds for sunlight, water and other soil minerals. There are also environmental factors that have an influence on seed germinability: during seed maturation, dispersal, storage and the imbibition of water. Although the majority of plants use other means to disperse their seeds, some plants explode in order to cause their seeds to spread. Seeds of many such plants are subsequently dispersed by ants, which is a common dispersal mechan-ism in these communities [16]. While we see self-dispersal of seeds in some plants, others require external agents for the same. These plants build up tension in their tissue, much like a catapult stores energy in a taut rope.

Some seeds literally use an explosion to disperse their seeds. At just the right moment, the tension is released and the seeds are flung. Strategies for seed dispersal: Ballistic .

These then drop off later after the animal has moved on. In the spring, the yellow pollen that coats your car is actually plant sperm. Seed dispersal is one of the most ecologically significant plant-animal mutualisms , , and it is central for understanding plant population and community structure and dynamics , .As with many other interspecific interactions , , seed dispersal by animals also involves both costs and benefits .Their balance determines whether the net outcome falls between mutualism or antagonism , .

These may affect the time and place of germination, as well as seedling survival, plant development, flowering, seed production and the termination of the life cycle at the right time. 1.
