afracturedreality:    Cross-section through the stem of Dracenea illustrating cellular relationships within the vascular tissue. Resources like water and nutrients traverse the plant via vascular bundles that are made up of many different cell types. Xylem fibers transport water and dissolved nutrients, while phloem fibers allow substances like sugar to move through the plant.  By John Runions, Oxford Brookes University

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.
