Question

Look at the experiment shown in Fig. Why was it necessary to take coloured eosin solution in water in the beaker?

Answer 1

The plant’s transport system consists of continuous vascular bundles in its stem, root, and leaf stalks. To show that water and salts migrate up the xylem, a coloured stain solution, similar to eosin, is used in a beaker. This coloured solution visualises and tracks the movement of water and salts in the plant’s vascular system, making the process easier to see.
