Take two small beakers and label them as A and B. Fill beaker A with water. Now
make a cylindrical-shaped roll from a filter paper and keep it as a bridge
between beaker A and beaker B, as shown in the figure. Attach few germinating
seeds in the middle of the filter paper bridge. Now, cover the entire set-up
with a transparent plastic container so that the moisture is retained.
Observation:
The roots of the germinating seeds will grow towards beaker A.
This experiment demonstrates the phenomenon of hydrotropism.
