 On the Wind: Plant Seed Dispersal

   Summary Author:  Menashe Davidson:

    Seed dispersal is an adaptive mechanism in all seed-bearing plants,
   participating in the movement or transport of seeds away from their
   parent plant to ensure the germination and survival of at least some of
   their seeds. It can take many forms, yet most dispersal mechanisms fall
   within the categories of gravity, wind, water, and animal
   dispersal. Species that use wind dispersal have a windsail-like
   structure, called the "pappus," that generally opens and closes in
   response to moisture. On dry, windy days the  pappus opens, catches
   the wind, and transports the seeds far away.

   Shown in the collage above are images of seeds, and pappus, of 4
   different species of plants, from different habitats. All of them have
   the same purpose – to transport the seeds far away from the mother
   plant.
