. [DOC] [TLE] Transpiration - Wikipedia [PAR] Transpiration is the process of water movement through a plant and its 
evaporation from aerial parts, such as leaves, stems and flowers. Water is 
necessary for plants but only a small amount of water taken up by the roots is 
used for growth and metabolism. The remaining 9799.5% is lost by transpiration 
and guttation. ... Soil water supply and soil temperature can influence stomatal 
opening, and... [DOC] [TLE] BBC - GCSE Bitesize: Plants and water [PAR] The absorbed water is transported through the roots to the rest of the plant where
