Water is an important transport and reaction medium.

Explanation: Water's polarity and solvent properties allow it to dissolve ions and polar molecules, enabling transport of nutrients, wastes and gases (e.g., in blood) and providing the medium in which biochemical reactions occur within the cytoplasm.
