Activity: cohesion of water what process exerts the pull on water molecules that is relayed from leaf to root via cohesion?

The process is EVAPORATION.
In plants, as each water molecule evaporate, it pulls up the next water molecules and this set up a chain reaction in which one molecule pull along the next one. This process is made possible by the cohesion property of water.
