This lesson teaches students about the different parts of a tree and their functions. It discusses how water and nutrients are transported through the xylem vessels and phloem tubes in the trunk to different parts of the tree. Specifically, it focuses on the xylem, phloem, sapwood and heartwood. The lesson provides key facts about each part and how they work together to support the tree. Students learn that xylem vessels transport water and minerals upwards from the roots while phloem tubes transport food made by the leaves throughout the tree. They also learn how sapwood and heartwood are formed as a tree ages.
