Design an experiment to demonstrate hydrotropism.

Q. Design an experiment to demonstrate hydrotropism.



Following things are required for this experiment:

Seeds of bean, a deep tray, sand, a porous flower pot



  • The tray should be big enough to accommodate the porous pot.
  • Fill the tray with sand and insert some seeds in it.
  • Make a pit in the sand and insert the porous pot in it.
  • Fill the porous pot with water.
  • Leave the set up for about a week.


After a week when seeds are taken out, it is observed that roots grow in the direction of the porous pot. This shows hydrotropic movement in roots.
