O It creates a brighter colored plant to

It attracts water to a plant without the

Answer 1

Plants utilize hydrotropism to bend their roots towards moistened areas of soil in the presence of moisture gradients (Takahashi et al., ; Moriwaki et al., ). Because roots play an important role in water uptake, hydrotropism may help plants to obtain water efficiently under drought conditions.
