One possible explanation for the reason water can be transported up the vessels in plants is because of adhesion of water to the lignified walls.

Question

Quizplus · Accepted Answer

Adhesion refers to the attraction between water molecules and the molecules of another substance, in this case, the lignified walls of the plant vessels. This adhesion, along with cohesion (the attraction between water molecules themselves), helps to pull water upward through the plant's vessels against gravity in a process known as capillary action.
