Question

Minerals are absorbed by plants in the form of

• A. Solid form
• B. Liquid form
• C. Gaseous form
• D. Ionic form

Hint:

Minerals are absorbed by plants as dissolved ions (ionic form) through root hairs.

Answer 1

The Correct Option is D

Plants absorb minerals from the soil primarily in ionic form dissolved in water. These mineral ions, such as nitrate (NO\textsubscript{3}\textsuperscript{-}), phosphate (PO\textsubscript{4}\textsuperscript{3-}), potassium (K\textsuperscript{+}), and others, are taken up by root hairs through active and passive transport mechanisms.
- Minerals are not absorbed in solid or gaseous form.
- Liquid form is a medium but not the chemical form absorbed.
