Question

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 1

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.
