Question
Water is able to travel against gravity, from the roots of a plant to the leaves at the top of the plant.Which of the following processes best explains the movement of water in this phenomenon?Choose 1 answer:Choose 1 answer:(Choice A) Surface tension, when the adhesive forces are stronger than the cohesive forces.ASurface tension, when the adhesive forces are stronger than the cohesive forces.(Choice B) Capillary action, when adhesive forces are stronger than cohesive forces.BCapillary action, when adhesive forces are stronger than cohesive forces.(Choice C) Surface tension, which occurs when the cohesive forces are stronger than the adhesive forces.CSurface tension, which occurs when the cohesive forces are stronger than the adhesive forces.(Choice D) Capillary action, which occurs when the cohesive forces are stronger than the adhesive forces.DCapillary action, which occurs when the cohesive forces are stronger than the adhesive forces.
Solution
The correct answer is (Choice B) Capillary action, when adhesive forces are stronger than cohesive forces. This process allows water to move upward in narrow spaces, such as the xylem in plants, despite the force of gravity. The adhesive forces between the water and the walls of the xylem are stronger than the cohesive forces between the water molecules, allowing the water to "climb" upwards.
