Which structure has stronger supporting force, xylem or phloem?

Xylem. Phloem is a complex tissue for transporting nutrients in vascular plants, which has the functions of support and storage. Phloem contains thick-walled tissue cells (including fibers and stone cells), and fibers are often distributed in bundles in phloem to increase its supporting ability. The xylem of trees is hard and plays the most important supporting role, and its supporting ability is stronger than both.
