Answer 1

The dissolved mineral salts in the xylem vessel are transported from the roots to the leaves by transpiration pull.

Step-by-step explanation:

The dissolved mineral salts in the xylem vessel are transported from the roots to the leaves by transpiration pull. Transpiration is the process by which water vapor is lost from the leaves, creating a suction force that pulls water and dissolved mineral salts up through the xylem vessels. This is aided by the cohesion and adhesion forces between water molecules and the xylem walls.
