Design an experiment to demonstrate hydrotropism


Q. No. 5: Design an experiment to demonstrate hydrotropism.
Ans:  Take a cubical transparent glass container and fill it with water. Now put some geminating seeds in it. After one or two days you will observe that the roots of all the geminating seeds will grow towards the water. This experiment proves that roots of germinating seed show the character of positive geotropism.
