Question

Quizplus · Accepted Answer

The movement of the blue dye through the celery stalk is due to capillary action, which is a result of water's adhesive and cohesive properties. Adhesion allows water to stick to the walls of the plant's vessels, and cohesion keeps the water molecules together, enabling the dye to travel up the stalk.
