vascular bundle

n.
A strand of primary conductive plant tissue consisting chiefly of xylem and phloem. Also called fibrovascular bundle.

vascular bundle

a structure of vascular plants that runs up through the roots, into the stems and out into the leaves, and whose function is transport within the plant. Water and ions are transported mainly by XYLEM, and dissolved organic solutes mainly by the PHLOEM. Some vascular bundles are described as open since they contain dividing CAMBIUM tissue between the xylem and phloem.

The hybrid's single layer epidermis, collateral vascular bundles, tetracytic stomata and tissue morphology were similar to those of the native species.
According to Gibelli (1876) and Gruber (1882) (sensu Solereder 1908) leaf folding is due to the fact that the lower epidermal cells, located in both lateral portions of the central vascular bundle, grow faster than the rest of the cells of both epidermis.
In a dicot plant stem, the vascular bundles are arranged in a ring that separates the cortex and pith (Figure 6-5).
Separating the cortex from the pith (both ground tissues) is a ring of vascular bundles (see Figure 7-10), the number of which is determined by the complexity of the tissue.
