Question

Capillary action can cause

• A. Water uptake in tall plants
• B. Water uptake in small plants
• C. Both of the above
• D. None of the above

Answer 1

The correct option is B Water uptake in small plants

Water tends to rise up inside the narrow tubes by capillary action. This is because of the cohesive force of the water molecules. Because of this water rises up in the xylem vessel to some distance up dragging other water molecules present below them this capillary rise cannot take up water to tall plants though this may be possible in very small plants. Thus, the correct answer is option B.
