hii dear.
plants have an ability to suck water by the means of osmosis.the water is an essential factor for the metabolic activities of whole plant.
However the sunlight and water are placed on the same side , the roots will always move towards water because , roots have to overcome water deficiency of plant. Its growth is always towards water , no matters where the sunlight is from.
the water present in underground sources causes roots to move downwards so we consider them as negatively phototrophic....but it's just due to underground water availability.

Sunlight can't reach the plant from below. Moreover the water we pour in are absorbed from the bottom.The above stated situation is not occurring.
