During the Fall in much of the country it's hard not to think about trees. Trees are beautiful, colorful and the leaves are everywhere. But when you think about trees do you also think about how trees work? Most of us haven't thought about the internal working of a tree since middle school science class, and these giant plants contain incredibly elaborate systems of cells and tubes. Xylem cells, phloem cells and stomata cells all working together to suck water up the tree like a straw.
Have you ever thought about how to use a straw? The longer the straw, or the smaller the hole, the tougher it is to get liquid through it. Trees can grow 300 feet tall and they get water all the way to their topmost branches. The question is, how the heck do they do it?!
