What is the main driving force for water transport in plants?
Root pressure
Transpirational pull
Water movement in the xylem
Water movement in the phloem
Solution
Most researchers agree that water is mainly "pulled" through the plant, and that the driving force for this process is transpiration from the leaves. This is referred to as the cohesion-tension-transpiration pull model of water transport.
