Design an experiment to demonstrate hydrotropism.

Design an experiment to demonstrate hydrotropism.

Dear Student

Take a tray filled with soil.
•Plant a seedling in the tray at one end.
•To the other end add water to the soil with the help of a pipe as shown in the figure.
Observation:The root (radicle) of the plant seedling moves towards the wet soil. This shows that roots are positively hydrotropic.

Thanks
