root, catclaw (Smilax), transverse section. Dark red stain - conjunctive tissue (cells that make matrix between tracheary elements and sive tube members are thick-walled fibers). Green - thin-walled sieve tube members and companion cells (arrows). Phloem alternates w/ masses of tracheary elements,near outer edge of xylem.
