How would you demonstrate hydro tropism with the help of an experiment?
Answers
The movement of a plant either towards or away from water is called hydro tropism. An example is that of plant roots growing in humid air bending toward a higher relative humidity level.

Answer:-
Hydrotropism:- It is the directional growth movement of curvature that occurs in response to the stimulus of water. The word is made up of 'hydro' which means 'water' & 'tropic' which means 'directional movement'. It is shown by roots and these roots are positively hydrotropic. Or Hydrotropism in simple words can be said as the downward movement of roots towards water.
Explaination:-
Test:-
Hydrotropism in roots can be tested by placing germinating seeds in moist soil dust contained in a seive then we will that radicles will pass down and move out of the seive pores under the influence of gravity.
But however after some period of growth they bend back and then enters the saw dust showing hydrotropic response. Also this experiment shows that hydrotropism is stronger than geotropism response. Hydrotropism can be seen in tomato roots, radish and carrot roots etc.
