How is it possible for water to defy gravity and travel from the roots to the tops of plants? Use the tension-cohesion model to explain your answer.
Tension-Cohesion Model
A theory explaining the movement of water through plants, where water molecules stick together (cohesion) and are pulled up the plant through tension.
Gravity
The force that attracts a body toward the center of the earth, or any other physical body having mass.

Final Answer :
Concepts to Consider: Evaporative pull of transpiration extends from leaves to stems and roots, drawing water upward; water is pulled up in an unbroken column due to the cohesive and adhesive properties of water.
