Explanation:Transpiration is the process in which moisture is carried through plants from roots to pores on the underside of leaves, where it changes to vapor and is released. Transpiration also provides a significant cooling effect which keeps the plant from being over heated.
Root pressure can transport water and dissolved mineral nutrients from roots through the xylem to the tops of relatively short plants when transpiration is low or zero. ... Xylem vessels sometimes empty over winter. Root pressure may be important in refilling the xylem vessels
