Question

with the help of an experiment, prove that roots are more positively hydrotropic than geotropic

Answer 1

Roots are more positively hydrotropic than geotropic because roots grow downwards in the direction of water.

Answer 2

EXPLANATION:  

The experiment that proves roots are more positively hydrotropic than geotropic is as follows, put a seedling on the soil and place a porous pot containing water near the seedling and leave the set up undisturbed for a few days, it will be observed after some days that the root grows towards the pot of water rather to the ground.

The roots always grow towards water so as to facilitate the plant with water required for photosynthesis.
