    Secondary Tissues in the Root

    The pine root below has one layer of periderm fully formed. Can you label the tissues and meristems described above? What are the large holes in the root?

    Figure \(\PageIndex{2}\): Cross section of a woody stem

    In the stem cross section above, label the following: pith, secondary xylem, xylem ray, vascular cambium, secondary phloem, phloem ray, cortex, phelloderm, cork cambium, cork, and epidermis. Next, indicate where the oldest and youngest xylem cells are located.

    Note: the newest cells will be located closest to the meristem that produced them!

    Where is the vascular cambium?
