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.
