the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it (negative phototropism ).

There are two types of phototropism: positive and negative.
Positive phototropism is growth toward a light source,
and negative phototropism is growth away from a light source.
Plant roots tend to exhibit negative phototropism, because they need to grow deeper into the ground for plant stability, water, and nutrients.
