The growth of all plants depends on a supply of water which is normally obtained through their roots from the soil. Plants use enormous quanities of water during their growing period, and although some of this water is used to carry soluble food into the roots and some is used to assist with carbohydrate production, the amounts used in these ways are small compared with the total consumption. For where a large proportion of other nutrients ~absorbed~by-the~plant-is~retained,~a~continuous_flow_ofwaterfrom~ the soil into the plant roots and out through the leaves must be maintained.
