Question

Movement of minerals in plant roots through diffusion is

• A. Endosmosis
• B. Osmosis
• C. Active absorption
• D. Passive absorption

Answer 1

The correct option is D Passive absorption

Diffusion helps in non-mediated passive uptake of minerals in plant roots. Diffusion is a free movement of ions in and out of the tissue. It helps in the movement of minerals from higher concentration to lower concentration without the help of any external metabolic energy.

So the correct answer is 'Passive absorption'.
