If you are a seed collector you probably have noticed the many ways Mother Nature has to disperse seeds to ensure a new generation of plants. Falling Fall from the Tree It is important for the seeds of many plants, especially perennials, to travel away from the parent plant—far from the tree.

Seed dispersal allows offspring to be spread over a wide area and decreases the competition between offspring. Seeds are dispersed in several different ways. In flowering plants like apple trees, one or more seeds are housed within a fruit. The fruit is the portion of the apple that we eat. Sweet fruit, like apples, are eaten by animals that.
Seed Dispersal Game
Description:
Bidens pilosa is an annual forb of gracile habit, growing up to 1.8 meters tall. It grows aggressively on disturbed land and often becomes weedy. The leaves are oppositely arranged and pinnate in form with three to five dentate, ovate-to-lanceolate leaflets. The petioles are slightly winged.[20]The plant may flower at any time of the year, but in temperate regions it blooms mainly in summer and autumn. Flowers are borne in small heads on relatively long peduncles. The heads bear about four or five broad white ray florets, surrounding many tubular yellow disc florets. The fruits are slightly curved, stiff, rough black rods, tetragonal in cross section, about 1 cm long, with typically two to three stiff, heavily barbed awns at their distal ends. The infructescences form stellate spherical burrs about one to two centimeters in diameter. The barbed awns catch onto fur or clothing, and can injure flesh. It is an effective means of seed dispersal by zoochory, as the seeds are transported by animals. This mechanism has helped the plant become a noxious weed in temperate and tropical regions.[20]
