Question

What facilitates the movement of water from soil to roots of plants?

• A. Water pressure.
• B. Presence of root hairs.
• C. Ion concentration gradient.
• D. All of the above

Answer 1

The correct option is C

Ion concentration gradient.

In soil, roots actively take up ions which create a difference between ion concentration in roots and soil. To eliminate this difference, water from soil moves into the root.
