stele
stele The vascular tissue (i.e. xylem and phloem) of tracheophyte plants, together with the endodermis and pericycle (when present). The arrangement of stelar tissues is very variable. In roots the stele often forms a solid core, which better enables the root to withstand tension and compression. In stems it is often a hollow cylinder separating the cortex and pith. This arrangement makes the stem more resistant to bending stresses. Monocotyledons and dicotyledons can usually be distinguished by the pattern of their stelar tissue. In monocotyledons the vascular bundles are scattered throughout the stem whereas in dicotyledons (and gymnosperms) they are arranged in a circle around the pith.

stele
stele The vascular tissue of a root or stem, consisting of a xylem, phloem pericycle, and sometimes having pith and medullary rays. Morphologically, steles can be divided into 2 main categories: protostele and siphonostele, the latter possessing a pith. Either type may be a single vascular vessel (monostele) or divided into several strands (dictyostele).
