chollenchyma
there could've been a high concentration of nutrients - such as salt - surounding the roots making it impossible for osmosis to occur
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die
