The movement of water, from one cell of cortex to adjacent one in roots, is due to (a) accumulation of inorganic salts in the cells (b) accumulation of organic compounds in the cells (c) water potential gradient (d) chemical potential gradient.
Option C Movement of water always occurs from low DPD to high DPD. During water absorption by roots, water as well as solutes enter through root hair. After absorption of water by root hair, its TP is increased and thus DPD or SP is decreased. Then water from root hair moves to the cells of the cortex along the concentration gradient and finally reaches the xylem
