Guess what my brother taught me!

Do you know why seeds don't sprout until after the winter?  It's because the plant produces a certain hormone in seeds which inhibits plant processes (i.e. growth).  Now, this particular hormone is rendered inert only after a long cold period (i.e. winter).  If this didn't happen then seedlings would sprout in the fall and be killed by winter frosts.  And do you know how desert plants manage the whole process?  The same hormone is present in the seeds, but rather than being rendered inert by cold it gets washed out with water.  So seeds only sprout after a heavy rain, otherwise they'd shrivel and die.

God is genius.

P.S.  Don't complain that this post isn't good enough, at least I'm posting again!
