Translocation of Solutes
Question

Which of the following technique can be used to confirm that minerals are mainly transported through xylem?

Easy
Solution

Mineral salts are translocated through xylem along with the ascending stream of water, which is pulled up through the plant by transpiration pull. Analysis of xylem sap shows the presence of mineral salts in it. Use of radioisotopes of mineral elements also substantiate the view that they are transported through the xylem.
