Water is a major part of cells, forming between 70 and 95% of the mass of the cell. ... In mammals, the alveoli in the lungs are moist with water, to allow gas exchange, and many plants have moist surfaces in their leaves (the mesophyll cells) for gas exchange. ... A main function is to transport materials around the body to where they are needed. ... Plants also lose water in a process called transpiration, and this helps water uptake by the roots, and has an effect on the temperature of the plant, and helps to ...
