Why does water form bonds with NO3- - Water is polar NO3- is negatively charged H bonds form between O on the nitrate and H from another water molecule How is it possible for water to move through and enter the epidermis - Ions enter the membrane against the concentration gradient This reduces the cell water potential Water moves by osmosis down the water potential gradient
