Answer:

Ions from soil reach to xylem of roots through active or passive uptake or a combination of both.  

Explanation:

Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.

Passive transport is the movement of molecules or ions from an area of higher to lower concentration.

Hope this helped!
