Answers
The dispersal mechanisms of seeds range from the simple dropping of the seed from the parent plant onto the ground to the more exotic ways such as scattering by wind or “shooting” from the plant. The tumbleweed scatters its seeds in the wind as it rolls along the ground. Light, puffy seeds like those of the thistle and dandelion and winged seeds like those of the maple and pine can ride the wind for great distances. Some seeds, such as the cocklebur, hitch rides on passing animals. Among the most exotic dispersal mechanisms are the “shooting” seeds of plants such as mistletoe or touch-me-not that are “spring loaded” and flung from the parent plant into the air.
For seeds used in farming and landscaping, the primary dispersal mechanism is the planter. This mechanism can be very simple such as the primitive dibble stick used to scratch open a furrow or poke a seed hole into the soil. At the opposite extreme is the modem mechanized planter that plants four or more neatly aligned rows at one time.
