Question

Use your knowledge of the cohesion-tension theory to explain how water in the xylem in the roots moves up the stem. ( 4 marks)

Accepted Answer

water evaporates/transpires; reduces water potential / creates water potential gradient / increases osmotic gradient / moves via apoplast pathway; water drawn out of xylem; creates tension/pulling effect / creates negative pressure (in context); cohesive forces or H bonding between water molecules / water moves as a column;
