Highlight structural differences and functions in the tree's protective

Cross-sectional diagram of a tree's bark layers. From outer to inner, it includes the rhytidome (outer bark), phellem (cork), phellogen (cork cambium), phelloderm, and secondary phloem. The image shows various cell types: parenchyma cells, sclerenchyma fibers, sieve tubes, and companion cells. Bark rays are visible, indicating pathways for nutrient transfer. Each layer is distinctly colored to highlight structural differences and functions in the tree's protective and transport system.
