Translocation of Nutrients

[Only1moomin]

Ever considered what happens to the sap at the leaf when 98% of the water drawn through evaporates away? Does it alter the density of the sap at the top of the tree? If not how is this possible? If yes why is it not mentioned in the science literature? Does a denser solution at the top of the tree migrate due to gravity and if so does this cause a return flow of less dense solution in the xylem? Of course it does! Google andrew k fletcher to get the true picture of circulation in trees & plants
