Roots grow towards the pull of what force
WebGeotropism is the influence of gravity on plant growth or movement. Simply put, this means that roots grow down and stems grow up. Geotropism comes from two words, “geo” which means earth or ground and “tropism” which means a plant movement triggered by a stimulus. In this case, the stimulus is gravity. Upward growth of plant parts ... WebJan 8, 2024 · Roots are termed positively geotropic; that is, they grow toward the direction of the pull of gravity.
