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. WebRoots of some plants do seek water, but gravity has an independent effect on the direction of root growth. Moreover, growing roots, which are strong enough to penetrate packed soil, are certainly strong enough to re sist the direct pull of gravity; root gravitropism arises from some other mechanism.
WebRoot response to gravity is positive geotropism (grows in the direction of the force of gravity). Auxin They are mostly made in the tips of the growing stems and roots, which are the meristems. WebThe roots are negatively phototropic, as they grow away from the light stimulus. High concentrations of auxin inhibit elongation of the cells at the bottom of the root, the opposite of its action in the shoot. This causes the cells at the top of the root to grow comparatively more, and for the root to bend downward away from light.
