EVERYDAY SCIENCE

Detailed explanation-1: -The xylem and the phloem make up the vascular systems found contiguously in the roots, stems (Fig. 1-3), and leaves of plants.

Detailed explanation-2: -The vascular bundles are arranged near the edge of the stem, with the phloem on the outside and the xylem on the inside.

Detailed explanation-3: -Plants don’t have blood vessels-instead they have xylem and phloem vessels. Xylem transports water whereas phloem transports glucose and dissolved amino acids. They are both specialised to carry out their function and arranged in such a way to give the plant as much structure and support as possible.

Detailed explanation-4: -The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root.
