Question:
Is it true that when a rainstorm is approaching, leaves will turn upward to catch raindrops?


Replies:
Leaves of some trees have stem structure and shape that causes them to turn in the kind of wind and air pressure that sometimes precedes storms, giving the appearance of turning upward. They do not catch any additional rain that way.
