1. To prove that the path of water transport is through the xylem vessels, a young balsam plant is taken and its roots are washed.
2. The roots of the plant are dipped in a 2% eosin solution.
3. After 3 – 4 hours, red streaks are observed on the stem and leaves of the experimental plant.
4. On cutting the section of the root of this plant, it is observed that the xylem appears colored which proves that the xylem is the path of the ascent of sap.
