Question

Inorganic nutrients are present in the soil in the form of

• A. Molecules
• B. Atoms
• C. Electrically charged ions
• D. None of the above

Answer 1

The correct option is C Electrically charged ions

Water and minerals ions are inorganic material present in the soil. The minerals exist as electrically charged ion because the root hair absorbs the mineral by passive absorption to outer space like intercellular space and cell wall but for absorption into the inner space like cytoplasm and the vacuoles, it needs active transport which requires ions to create a concentration gradient. The electrically charged mineral ions help to maintain the concentration gradient and allows easy absorption through active transport.

So, the correct answer is option C.
