Question

Bidirectional translocation of solutes takes place in

(a) parenchyma

(b) cambium

(c) xylem

(d) phloem.

Answer 1

Option d is correct

Explanation :

The movement of organic food or solute in soluble form from one organ to another organ is called translocation of solutes, e.g., from leaves to stem and roots for consumption.

The movement of organic material is bidirectional.

Because xylem is responsible for upward movement of water and minerals, so it cannot account for downward translocation of solute at the same time. Cortex and pith are not structurally suitable for this purpose.
