Answer: Hydrotropism is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. A common example is a plant root growing in humid air bending toward a higher relative humidity level. the growth or turning of plant roots towards or away from moisture.
Plants utilize hydrotropism to bend their roots towards moistened areas of soil in the presence of moisture gradients. Because roots play an important role in water uptake, hydrotropism may help plants to obtain water efficiently under drought conditions.
