A heating sleeve was fitted around the trunk of a small tree at a height of $1\,\text{m}$ above the ground. This made it possible to warm a narrow section of the trunk to $60\,^{\circ}\text{C}$. How would heating this section to $60\,^{\circ}\text{C}$ affect the movement of phloem sap and xylem sap between the roots and leaves?
