GCSE BiologyCell Biology

Explain how water moves into a plant root cell. (4 marks)

AI FeedbackExample

3 / 4

“You clearly explained where the water moves from, the water potential gradient and osmosis itself. To achieve full marks, you needed to name the structure the water passes through.”

Improvement tip:

• Missing structure: state that the water enters through the partially permeable cell membrane.
• Precision with terminology: be explicit that water moves from a region of higher water potential in the soil to lower water potential inside the cell.
