Question

rationalization of 2(√7-1)/(√5+2)​

The concentration of water in the surrounding is more than that of the interior of the cell; this causes the water from the surrounding to move in because of endosmosis.Read more on Sarthaks.com - https://www.sarthaks.com/135023/the-diagram-below-represents-a-layer-of-epidermal-cells-showing-a-fully-grown-root-hair
