Question

1. 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 enables it to move from the roots to the leaves of plants?

water expands as it freezes.
water is an excellent solvent.
water exhibits cohesive behavior.
water is able to moderate temperature.

Explanation:

Cohesion is the attraction between molecules of the same substance. In plants, cohesive behavior of water allows water molecules to stick together and form a continuous column, enabling water to move from the roots to the leaves through xylem vessels against gravity. Expansion on freezing, being a good solvent, and temperature - moderation properties are important for life but not directly related to this upward movement.

Answer:

Water exhibits cohesive behavior.
