Detailed explanation-1: -ii. Xylem translocates mineral salts along with descending stream of water.

Detailed explanation-2: -The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw. Cohesion (water sticking to each other) causes more water molecules to fill the gap in the xylem as the top-most water is pulled toward the stomata.

Detailed explanation-3: -The tube-like structure called xylem is present in the stem that carries water to all the parts of the plant.
