What is the inside of tree bark called?
phloem

What is under the bark of a tree?
Phloem is right below the surface bark and carries sugars from the leaves down to the rest of the tree. Further in is more ‘plumbing’ called the xylem or sapwood. These tubes carry water and minerals the opposite way, up to the leaves. Sandwiched between these two layers is the cambium.
Why do trees have different types of bark?
As a tree grows, its wood thickens and pushes out against the bark that surrounds it. The different ways in which the outer bark adapts to this pressure is what gives each species its distinctive appearance. Some species maintain their original outer layers (the initial periderm) for their entire lives.
What is the central core of a tree called?
Heartwood lies at the center of the tree; it is the central pillar supporting the tree. Heartwood is a composite of hollow, needle-like fibers bound by the tree’s natural chemical glue, lignin.
Is bark xylem or phloem?
Both inner bark (secondary phloem) and wood (secondary xylem) are generated by the vascular cambium layer of cells: bark toward the outside where the oldest layers may slough off, and wood toward the inside where it accumulates as dead tissue.
What is maple bark?
