Roots obtain cations through cation exchange. Which of the following do roots use to exchange for other cations from the soil?

Question

Quizplus · Accepted Answer

Roots use hydrogen ions (H+) to exchange for other cations from the soil through a process called cation exchange. Therefore, the correct option is (C) H⁺, which represents hydrogen ions. Option (A) Cl- is an anion, not a cation, and therefore is not involved in cation exchange. Option (B) and (D) are not chemical formulas or ions commonly involved in cation exchange in plants.
