Question

water is essential for life. its special properties make water the single most important molecule in plant life. which of the following properties of water enable it to move from the roots to the leaves of plants? water is an excellent solvent water exhibits cohesive and adhesive behavior water expands as it freezes water has a high heat capacity

Explanation:

To determine which property of water enables it to move from roots to leaves in plants, we analyze each option:

• "Water is an excellent solvent" relates to dissolving substances, not water movement in plants.
• "Water exhibits cohesive and adhesive behavior": Cohesion (water molecules sticking to each other) and adhesion (water molecules sticking to the xylem walls) create a continuous column of water and allow capillary action, which is essential for water transport from roots to leaves (transpiration - cohesion - tension mechanism).
• "Water expands as it freezes" is about water's behavior when solidifying, not transport in plants.
• "Water has a high heat capacity" is about temperature regulation, not water movement.

So the property related to water movement in plants is its cohesive and adhesive behavior.

Answer:

Water exhibits cohesive and adhesive behavior
