how are water and mineral trasported in plants?
Asked by | 20th May, 2009, 10:35: PM
The xylem is responsible for the transport of water and soluble mineral nutrients from the roots throughout the plant. It is also used to replace water lost during transpiration and photosynthesis. Xylem sap consists mainly of water and inorganic ions, although it can contain a number of organic chemicals as well. Two phenomena which cause xylem sap to flow are transpirational pull and root pressure.
