vascular bundle
World Encyclopedia | Date: 2005
vascular bundle Strand of conductive tissue that transports water and dissolved mineral salts and nutrients in a
vascular plant. They extend from the roots, through the stem, and out to the leaves. They consist of two types of tissue:
xylem, which conducts water from the roots to the shoot and is located towards the centre of the bundle; and
phloem, which conducts salts and nutrients and forms the outer regions of the bundle.

; The outer tissues of dicotyledonous plant roots (i.e. epidermis, cortex, and endodermis) are clearly organized in distinct concentric layers in contrast to the diarch to polyarch vascular tissues of the central stele. Up to now, the outermost layer of the stele, the pericycle, has always been
