Water and dissolved minerals are conducted from the roots to the stems and leaves via xylem, whereas sugar is conducted through specialized cells known as sieve tubes.
Water is drawn up from the roots to the top of the plant according to the cohesion-tension theory of sap ascent. Water and minerals travel upward from the roots through the xylem due to a negative water potential gradient created by the evaporation of mesophyll cells in the leaves.
Specialized cells known as sieve elements play a crucial role in the operation of phloem, a highly organized tissue that transfers organic chemicals produced during photosynthesis. In phloem, sieve elements are the main conducting cells. Conducting cells support molecular transport, particularly for long-distance signalling. There are two basic categories of sieve components in plant anatomy. Meristems, which are tissues that actively divide throughout a plant's lifecycle, are the source of companion cells and sieve cells. They resemble the growth of xylem, a plant tissue that conducts water and serves primarily as a means of transportation within the vascular system.
Hence, transport of water and food is transported in two different pathway.
