Pine tree sap

Sap is like the lifeblood of a tree. It helps carry nutrients through the tree to where they are needed most. Roots are constantly pulling in water, minerals and other nutrients that need to be spread throughout the tree, especially to the leaves. Leaves, meanwhile, are producing simple sugars and need a way to transport through the tree fibers and get rid of their waste products. Sap is used to carry these compounds to where they are needed. It moves much slower than blood does, and is of a much thicker consistency.
