A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in vascular tissue, which exists in two forms: xylem and phloem.Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues.The xylem typically lies adaxial with phloem positioned abaxial. In a stem or root this means that the xylem is closer to the centre of the stem or root while the phloem is closer to the exterior.he transport itself happens in vascular tissue, which exists in two forms: xylem and phloem.

Vascular or conductive tissue is a distinctive feature of the complex plants, one that has made possible their survival in the terrestrial environment. Vascular tissues are co â¦ mmonly known as Xylem & Phloem.ach network consists of a different type of vascular tissue that works to move different resources throughout the plant.     These vascular tissues would be the tissues known as xylem and phloem. 11 people found this useful.
