How Does Tracer Dye Move Through Plants? | Xylem Transport Explained

Tracer dye can travel through plants by being absorbed through the roots and transported through the xylem tissue to the rest of the plant. The xylem is responsible for transporting water and nutrients from the roots to the leaves. Therefore, the tracer dye would primarily travel through the xylem vessels, moving against gravity from the roots upwards through the stem and into the leaves.
