Question

Force developed in cortex of root, which pushes water into xylem of root from soil

• A. Diffusion
• B. Osmotic pressure
• C. Turgor pressure
• D. Root pressure

Answer 1

The correct option is B Osmotic pressure

Water moves from a region of high water potential towards the region of low water potential. In root cortex cells due to the accumulation of solutes, osmotic pressure builds up and water potential decreases. Consequently, water moves in through the cells by the process of osmosis.

So, the correct answer is option B.
