WebRoots show positive gravitropism, which means they always grow towards the pull of gravity. This is observed in all plants, their roots always grow towards the pull of gravity and never away from it. This is necessary so that the roots grow In the soil which is where the roots can uptake nutrients for the plants survival. 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.

WebIn a root placed horizontally, the bottom side contains more auxin and grows less - causing the root to grow in the direction of the force of gravity. This is just like phototropism, in... WebRoots. The general perception is that roots are the parts of the plant that are found in the soil. While this is typically true, there are exceptions, just as there are with the notion that all shoots are above ground.
