I just watched a time lapse video of a pumpkin reaching full maturity. What takes 108 days can be seen in the span of four minutes. What's remarkable to me is how the leaves of the plant expand and contract as each day begins and ends. It looks like what a lung does every time it draws in air and breathes it out. This shouldn't be very surprising, because each method whereby an organism obtains energy does so at the rate of its metabolism. It was just remarkable to witness that for the first time.
