Explanation: 

Detailed explanation-1: -Xylem is located in the centre of the vascular bundle, deep in the plant. Phloem is located on the outer side of the vascular bundle.

Detailed explanation-2: -It transports water upward from the roots to the leaves. Phloem is the tissue that transports the carbohydrates (sugars) produced in photosynthesis throughout the plant. In roots it is usually found in between the xylem in the vascular cylinder.

Detailed explanation-3: -Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the center of the plant, forming a vertical column that conducts water and minerals absorbed by the roots upward through the stem to the leaves.

Detailed explanation-4: -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.

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.
