How Trees Drink Without Any Hearts

Plants move water hundreds of feet into the air without a single pump. They rely on solar power to pull moisture up from the roots, creating a continuous chain of water molecules that defies gravity.

This process works because water molecules are naturally attracted to each other, acting like a long, unbroken liquid rope. As water evaporates from tiny leaf pores, it tugs on the rest of the chain, drawing more liquid up through the stem. It is a passive miracle that allows giant trees to sustain themselves using only the sun and air. This invisible mechanism is so efficient that it can move massive volumes of water upward throughout an entire forest.
