Question

Which example best shows that the chemistry of water is helpful to plants?
Water’s polarity produces a high density, which allows water to move to the leaves.
Water’s bent shape causes a slow passage of nutrients up to the leaves of plants.
Water’s polarity causes cohesion that pulls other water molecules up through a plant.
Water’s bent shape reduces its own passage through the cell membranes of roots.

Answer 1

"Water’s polarity causes cohesion that pulls other water molecules up through a plant."

Explanation: Water molecules are polar and form hydrogen bonds, causing cohesion (water molecules sticking to each other). During transpiration, cohesion allows a continuous column of water to be pulled up through xylem from roots to leaves.
