THE MIRACLE IN THE SEED












                                                                   The Terminalia
                                                                   plant has V-shaped
                                                                   wings.




                                                  When the airplane was invented, in-
                                                  spiration was taken from birds. The
                                                  inspiration for a helicopter came from
                                                  dragonflies, and from plant seeds
                                                  that spin around a central point.
                                                  Pictures are examples of seeds of
                                                  plants that disperse their seeds by
                                                  air.


                                                  Maple seeds hang on the tree like
                                                  pairs of wings.


                stay longer in the air. When the wind drops, the seeds spiral slowly to
                the ground. As the European maple is thinly dispersed in the region
                where it grows, the wind is one of the main aids in its dispersal.
                Thanks to this feature, the helicopter seeds, which are created to spin
                even in a light breeze, can sometimes travel many kilometers. 27
                    The  Terminalia calamansanai  has seeds with V-shaped wings,
                thanks to which they can glide on a gentle air current much like a pa-
                per plane. 28


                    Parachute Seeds

                    People jump from great heights safely, with parachutes whose
                specially designed shape lets the user glide through the air. Some seeds
                also have similar structures.
                    When they mature, parachute seeds do not immediately fall to the
