Xylem and Phloem are the Vascular Tissues in MOST plants . They are usually found together.
Most people are familiar with vascular tissues in stems.
Thus we will start with stem cross-sections. The vascular tissues in stems are found within bundles which are continuous over a relatively large distance. Cells in the xylem have thick lignified walls which stain red for lignin in most preparations. Both Xylem and Phloem have cytological traits which distinguish them from the surrounding tissues. The Lignified walls of the Tracheary Elements in the Xylem are the most distinctive of these.
