The vascular bundle in which xylem and phloem are remain together in such a way that one encloses the other. In older plants the xylem bundles fuse together to form the bulk of the stem. The vascular bundle in which xylein and phloem are together present and remain side by side is called conjoint, collateral. Vascular bundles (VB) are the components of vascular tissue system in plants. Collateral vascular bundle: A type of conjoint vascular bundle where the xylem occupies inner to a single strand of phloem.

The plant tissues transport water and nutrients that are pumped through the plant's whole structure, often against gravity. The stem has to resist compression (squashing) and bending forces caused by the plant’s weight and the wind. ii) There is no cambium present in between xylem and phloem, so these vascular bundles are always closed. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves.
