The transportation of food (mainly sugars produced through photosynthesis) in plants is primarily facilitated by the phloem tissue, which is part of the plant's vascular system. The movement of food substances, such as sugars, from the sites of production (usually the leaves) to other parts of the plant, is known as translocation. 1.

Water moves only in the upward direction when absorbed by roots through the xylem. Hence, water transport is unidirectional. Food is transported by the phloem tissue. Food is synthesised in leaves and required by both roots and shoot system; thus, phloem sap moves upwards as well as downwards making food transport bidirectional so that it can
