Roots grow towards the pull of what force

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.
