Concept Explanation
 

Geotropism Movement

Geotropism is the tropic response of organisms due to gravity. When a growing portion of a plant is placed horizontally, the stem tip grows away from the pull of gravity, while the root tip grows towards it. Thus, the stem is said to be negatively geotropic and the root positively geotropic. The hydrotropic movements are more stronger then the Geotropic movement therefore the roots will grow inside the soil in the direction of water available.
