Question

what favours translocation in plants explain

Answer 1

in the plant translocation is will be defined transfer of hormone and food one place to other place

Answer 2

According to the classical concept inorganic solute substances are carried in the xylem vessels with the ascending sap of water in the transpiration stream whereas phloem is the pathway of downward translocation of organic solutes (synthesised foods like sugars, amino acids, etc.).

Translocation of Inorganic Solutes:

The classical concept of movement-of inorganic solutes upwards through the xylem is unquestionably true but it is difficult to estimate with certainty the proportion of mineral salts thus translocated. Any solute conducted through the xylem is carried along with the ascending streams of water which are pulled up through the plant by transpirational suction.
