Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration-against the concentration gradient. Active transport requires cellular energy to achieve this movement. In Option D, the molecules enter the Root Hair Cell although the mineral ions are in higher concentration inside the cell.
