Quizplus · Accepted Answer

The bark of a tree trunk is made up of secondary phloem and layers of periderm. Secondary phloem is responsible for transporting food from the leaves to the rest of the tree, while periderm is responsible for protecting the tree from external damage and water loss. Heartwood and sapwood are found in the inner layers of the tree, not in the bark.
