The xylem carries water and mineral nutrients mainly upward in the plant or from roots to shoots. Xylem consists of dead hollow cells stacked end to end to form "pipes." The phloem mainly moves organic compounds, such as sugars, but can move them in any direction required. The phloem can also redistribute some mineral nutrients. Phloem cells are living while they function.
