How a Tree Works

Certified Arborist Wes Hopper explains the basics of how trees work. Trees use photosynthesis to convert nutrients into sugars for the tree to use. Wes also explains how the vascular system in the tree transports water and nutrients from the roots up to the leaves, and the sugars from photosynthesis from the leaves to the other parts of the tree. Wes shows the different layers of a tree trunk and talks about what each layer does. He talks about the different kinds of roots and what they do. Wes also talks about how trees react to high summer heat.
