Geotropism is the growth movement in plants in response to the force of gravity.
The negative geotropism is defined as the upward growth of the plant's part against gravity. Stem is example of negative geotropism.
The positive geotropism is defined as the downward growth of roots. Root is example of positive geotropism.
Although most roots show positive geotropism, but there are some plants in which the roots are negatively geotropic. e.g. Coralloid roots of Cycas. In such plants, the auxin concentration is less. As a result, plants show upward movemnet of roots.
