      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.
