Seedlings normally emerge in the early morning, why ?

Seeds must germinate some time between planting and emergence, the question is are the plants programed to take advantage of as much sunlight on their first day in the world or it some thing else ?

Another question that comes to mind is how do plants "know" which way is up before the light can show them the way ?

That survival of the plant relies on getting things "right" is obvious.

If it is easier than explaining it all (because if you can answer these how and why questions I will be back for more !) please point out a web site or a subject area at the library.

I grew up on a farm and went to an Agricultural high school, but it is only now that these questions come to mind !
