The growth of plant parts towards or away from water is called hydrotropism. Roots are positively hydrotropic, i.e., they grow towards water in the soil. The positive hydrotropism of roots is stronger than their positive geotropism .Due to hydrotropism, the roots of roadside trees often block leaking sewage drains. The growth of stem away from the water is an example of negative hydrotropism.
We take two glass troughs A and B and fill each one of them two -third with soil. In trough A we plant a tiny seedling. In trough B we plant a similar seedling and also place a similar seedling and also place a 'clay pot' inside the soil. Water the soil in trough A daily and uniformly. Do not water the soil in trough B but put some water in the clay pot buried in the soil. Leave both the troughs for a few days. Now, dig up the seedlings carefully from the both troughs without damaging their roots. We will find that the root of seedling in trough A is straight. On the other hand, the root of seedling in trough B is found to bend to the right side.
