Stain test shows that lot of water passes through living cells of xylem.

Answer 1

2. After 3 – 4 hours, red streaks are observed on the stem and leaves of the experimental plant.
3. On cutting the section of the root of this plant, it is observed that the non-living or the dead cells of the xylem have taken up the stain.
