Which of the following does not contribute to forming the curved upper surface of water inside a narrow tube such as a tracheid or vessel?

Question

Quizplus · Accepted Answer

The curved upper surface of water inside a narrow tube, known as meniscus, is primarily formed due to the cohesive forces between water molecules and the adhesive forces between water molecules and the tube wall. Gravity does contribute by pulling the water column down, and cohesion pulls the topmost water molecules downward, enhancing the curve. However, atmospheric pressure acts uniformly on the water surface and does not contribute to the curvature; instead, it affects the overall level of water in the tube.
