what is translocation of solutes_??
Answers
Answer:
TRANSLOCATION OF SOLUTES
Mineral salts are translocated through xylem along with the ascending stream of water, which is pulled up through the plant by transpirational 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.

ANSWER
Translocation of water and minerals in the xylary elements is always unidirectional, i.e., upwardly from roots to aerial parts. The driving force for transport in xylary elements is transpiration.
Translocation of organic solutes in phloem is bidirectional. The transport of prepared food is from source to sink. The source is the area, where sugars are present in larger amount either because they are synthesized there, example leaves or are stored there, example storage organs.
Sink is the region of sugar utilisation. Where ever sugars are present in higher concentration, from there, sugars will be transported to a region, where sugars are required or need to be stored. Thus, the transport is bidirectional.
