Question

Which among the following statements are correct with respect to root pressure?

• A. Root pressure is generated in the roots and helps drive water in both directions.
• B. Root pressure helps in continuous movement of water through xylem.
• C. Root pressure is responsible for the ascent of sap in plants.
• D. Root pressure can push water up to small heights in a plant.

Answer 1

Answer: (B), (C), (D)

Root pressure can push water up to small heights in a plant.

Root pressure is a force or the hydrostatic pressure generated in the roots that help in driving the fluids and other ions from the soil in upwards directions into the plant’s vascular tissue – Xylem.
Root pressure helps in continuous movement of water through the plant's vascular tissue-xylem. It can push water to small heights and is responsible for ascent of sap.
