Xylem Cell Diagram. Vessel elements are shorter and are connected together into long tubes that are called vessels. When this happens the primary xylem cells die and lose.
When this happens the primary xylem cells die and lose. Four independent phloem strands grow between each bar of the xylem cross. Between two parenchyma cells the pit is obviously simple.
The structure of xylem and phloem is also different.
It carries water absorbed by roots from soil to different parts of the plant body. Its job is to make sure water flows upward. Xylem formation begins when the actively dividing cells of growing root and shoot tips apical meristems give rise to primary xylem in woody plants secondary xylem constitutes the major part of a mature stem or root and is formed as the plant expands in girth and builds a ring of new xylem around the original primary xylem tissues. It is the specialized tissue of vascular plants that transports water and nutrients from the plant soil interface to stem and leaves and provides mechanical support and storage.
