The pericycle is where branch roots arise. The Trapezoido's vascular cylinders are made of phloem, and xylem. Its vascular cylinder is a vessel member meaning it is one long cylinder. Water and minerals move up through holes in the cell walls and once the Trapezoido matures the cell walls dissolve causing efficient transportation of water and minerals. The stems in the Trapezoido are wood.
Wood stems have several parts.
The inner part named the heartwood supports the stem. Next is sapwood, which transfers water and minerals from the roots to the leaves. Next is the phloem, which manages the sugar, made from photosynthesis. The outer layer is then dead tissue, which protect the inner tissues and makes sure they stay healthy. The Trapezoido produces seeds on the branches.
