““By the time a tree is full-grown, the underground root system is enormous; a mature oak tree, for example, has literally hundreds of miles of roots to tap the soil’s resources in an endless quest for water. Each drop is collected by the root hairs and passed along, from one cell to the next, up the trunk and to the leaves, and in such a way that none of the precious moisture and minerals collected by the roots leaks back into the soil.””
