| Title: | Web Tutorial 36.1 Solute Transport in Plants |
| Caption: | Plants have a coordinated system for moving water and solutes to the structures where they are needed. Xylem transports water and minerals upward from the roots to the leaves. Phloem transports sugars downward from the leaves to where they are used or stored (the roots and fruits). This tutorial demonstrates how water and solutes move in both xylem and phloem. |
