Blooming of the pine cone

Blooming of the pine cone

I picked up a few of these pine sp. cones in Nainital a couple of days back. And these are the before and after images of the pine cones when i brought them back to Bombay.

As you can see, the cones closed up.
I started thinking of that and came up with a few questions

  1. How does a pine cone bloom, what is the mechanism of this blooming. I know it has everything to do with relative humidity. But what?
  2. How does a flower bloom?
