Tree Trunks

Tree trunks are the main support structure of a tree, acting like a strong, central column that holds up the branches and leaves. They contain tissues called xylem and phloem, which transport water, nutrients, and sugars between the roots and the rest of the tree. The trunk is made of wood and bark; the bark protects the tree from injury and disease. As trees grow older, their trunks become thicker and more durable, providing stability and strength. Essentially, the trunk is vital for the tree’s structural integrity and the distribution of essential resources throughout the organism.
