What is transpiration pull theory?
ASCENT of XYLEM SAP: Water transported up from the roots must replace water lost by transpiration. WATER POTENTIAL: Xylem sap rises against gravity, driven by a gradient of water potential (*) Water flows from an area of high * to an area o... Read More »

What is transpiration pull?
Water is continually being lost from leaves by transpiration. This loss of water in the leaves exerts a pull on the water in the xylem ducts and draws more water into the leaf. Source(s): http://users.rcn.com/jkimball.ma.ultrane… Read More »
