Detailed explanation-1: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves. Xylem is responsible for the transport of water and dissolved ions from the roots upwards through the plant.
Detailed explanation-2: -Unlike xylem which is unidirectional, the movement in phloem is bi-directional.
Detailed explanation-3: -Xylem and Phloem are called conducting tissues because they are involved in the conduction of water and the food. Xylem is responsible for the conduction of water absorbed by the roots to different parts of the plant. Whereas phloem conducts food prepared in the leaves to various parts of the plant.
Detailed explanation-4: -phloem, plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, phloem fibres, and phloem parenchyma cells.
