1) The answer is phloem.
Reason: root hair, root and xylem are involved in the process of absorption of water and the movement of it whereas, the phloem of the plant is involved in the translocation of food.
2) The answer is translocation
Reason: In osmosis, wilting and transpiration water moves from either one cell to the other cell or it will change its states from liquid to gaseous formation. But the translocation is totally different between them. It involves the movement of the food in the plant body.
3) The answer is copper.
Reason: Nitrogen, phosphorus and calcium are essential nutrients required for the growth of the plant. whereas, copper is a metal.
