Final answer:
Hydrogen bonding is the property of water that allows it to move up through a plant.
Step-by-step explanation:
The property of water that allows it to move up through a plant is hydrogen bonding. Water molecules are attracted to each other through hydrogen bonding, creating a strong cohesive force. This cohesion, along with the adhesive force between water molecules and the cell walls of the plant's xylem vessels, allows water to move upwards against gravity through capillary action. The hydrogen bonding between water molecules also helps create surface tension, which further aids in the movement of water up the plant.
