vascular bundle

vascular bundle in botany, a strand of conducting tissue extending lengthwise through the stems and roots of higher plants, including the ferns, fern allies, gymnosperms, and angiosperms. The vascular bundle consists of xylem, which conducts water and dissolved mineral substances from the soil to the leaves, and phloem, which conducts dissolved foods, especially sugars, from the leaves to the storage tissues of the stem and root. The structure of vascular bundles varies among the different plant groups. See wood .

vascular bundle (fascicle) A long continuous strand of conducting (vascular) tissue in tracheophyte plants that extends from the roots through the stem and into the leaves. It consists of xylem and phloem, which are separated by a cambium in plants that undergo secondary thickening. See vascular tissue.

vascular bundle A discrete, longitudinal strand that consists principally of vascular tissue (xylem and phloem). Groups of these form a continuous conductive system throughout the plant along which water and soluble nutrients pass. This vascular system also contributes to the structure support of the plant.
