Water is the major constituent of any living organism and the maintenance of a plant with optimum water content is a very important part of plant growth and development (see Soil Water, Chapter 19). Probably more plants die from lack of water than from any other cause. Minerals are also raw materials essential to growth (see p126), and are supplied through the root system.
