Detailed explanation-1: -A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, 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.

Detailed explanation-2: -organized into discrete strands called vascular bundles, each containing xylem and phloem. In stems, the vascular tissue is organized into many discrete vascular bundles. In the roots, the vascular tissue is organized within a single central vascular cylinder.

Detailed explanation-3: -The vascular bundle is known as conducting vessel of a plant. The vascular bundle consists of the xylem and phloem. They aid in water and dissolved mineral absorption, as well as their transmission to the stem and the storage of reserve foods. In the vascular bundle, phloem and xylem are separated by only a few cells.

Detailed explanation-4: -So, the correct answer is ‘Concentric leptocentric/amphivasal.

Detailed explanation-5: -The vascular bundles are arranged near the edge of the stem, with the phloem on the outside and the xylem on the inside.
