Cohesion-tension theory regading ascent of sap was given by

• A. Dixon and Jolly
• B. J.C. Bose
• C. Christian Wolf
• D. Godlewski

Answer 1

The correct option is A Dixon and Jolly

Cohesion tension theory is a theory of ascent of sap. It was originally proposed by Dixon and Joly in 1894.

This theory is quite convincing and has been widely accepted. As the name suggests, the cohesion theory is based on the force of cohesion between water molecules. This forms a continuous water column throughout the xylem vessels of the plant, from the top to the root.
