Tropism is the growth response of a plant caused by a stimulus. Gravitropism is the growth response of plant to gravity. The roots grow downward towards gravity, which is called positive gravitropism. The stem and upper part of a plant grow upward, away from gravity, which is called negative gravitropism.
