What is the texture of the stem and branches of the oak tree?

The texture of the stem and branches of an oak tree is generally rough and coarse, characterized by deeply furrowed bark that can vary in color from gray to brown. The bark often develops ridges and plate-like scales as the tree matures, providing a rugged appearance. Young branches may be smoother and more flexible, while older branches become increasingly textured and sturdy. Overall, the texture contributes to the oak tree's resilience and longevity.
