Solution(By Examveda Team)
The cohesion-tension theory was proposed by Dixon and Jolly.The cohesion-tension theory (C-T theory) by Boehm (1893) and Dixon and Joly (1894) postulates that the water ascent in trees is exclusively due to the transpirational pull from continuous water columns in the xylem conduit running from the roots to the leaves.
The cohesion-tension hypothesis states that transpiration drives xylem water flow. Negative water potential attracts soil water into root hairs and xylem. Water is drawn up the xylem by cohesion.
