Transcribed Image Text:The center of the woody stem is called the pith. Over the years it gets very
hard and becomes clogged with resin. This seals out moisture. This center wood is
called heartwood. The outer, newer wood is called sapwood.
The bark of the tree is very interesting. Different trees have different bark.
You can sometimes tell a tree by its bark. Bark is all the tissue between the
cambium and the outer surface of the stem. Bark is divided into two sections, inner
and outer bark. The outer bark, which is what you see, protects the tree from
disease and the environment. This outer bark is actually dead cork tissues. The
inner bark is living tissues like cork cambium, cortex, and phloem. As new cork tissue
develops from the cork cambium, it pushes out on the dead cork tissue of the outer
bark. This causes the outer bark to crack. This forms the unique patterns on the
barks of trees.
