Back on the farm we use to plant corn [sweet & field corn]. The corn would come up and the growing conditions were just right you could sit in the corn patch at night when the daily background noises were gone you could hear the corn stalks growing.

You think seeds and plants do not think? Think again. You ever see a kernel of oats in its husks with the two feelers sticking out. If that oat seed was laying on top of the ground those two feelers would reach down to the ground and push the oat seed down into the ground.

You ever watch leaves on a tree before a rain storm? The leaves will turn themselves over.
