In tall plants translocation of minerals occur from old leaf to young leaf by(1) Xylem (2) Simple diffusion (3) Phloem (4) Cytoplasmic streaming

Answer»

The correct option is (1) Xylem.

  • The xylem, vessels, and tracheids of the roots, stems, and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. 
  • The system transports water and soluble mineral nutrients from the roots throughout the plant. 
  • Hence, Mineral translocation in plants occurs through Xylem.
