Heartwood
The darker wood in the center of a tree trunk is called the heartwood. It is made up of older xylem cells that have become inactive and no longer conduct water, but provide structural support to the tree.
The wood in the trunk and limb of a tree is made up of xylem tissue. Xylem is responsible for conducting water and nutrients from the roots to the rest of the tree. It also provides structural support to the tree.
Tree rings are formed by the growth of two types of vascular tissues: xylem and phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem helps transport sugars and other nutrients produced in the leaves to other parts of the tree. The formation of these tissues in a tree's trunk leads to the annual growth rings that can be seen in the cross-section of a tree trunk.
Xylem is the layer of wood in a tree next to the heartwood (dead center of a tree) and it carries water down and up the tree.
The oldest and hardest wood in a tree trunk is usually found in the center of the trunk and is called the heartwood. Heartwood is darker and denser than the outer layers of the trunk and provides structural support and protection for the tree.

Secondary Xylem
A tree trunk is primarily made of xylem, which is responsible for transporting water and nutrients from the roots to the rest of the tree. Phloem, on the other hand, is responsible for transporting sugars produced through photosynthesis from the leaves to other parts of the tree.
Cambium produces xylem and phloem. the tissue you want is xylem

Cellulose is the fibrous material. Xylem is another component.

Trunk of any tree is its heart. In other words, It contains number of xylem and phloem which nourishes all the leaves of a plant. Outer covering of trunk serves the function of protection.
