What role does water play in living organisms?

Water is essential for the survival of living organisms primarily because it serves as a medium for biochemical reactions and is pivotal in maintaining cell structure. In biological systems, many crucial chemical reactions, including metabolic processes, occur in aqueous environments. Water facilitates the movement of molecules and ions, allowing for processes such as nutrient transport and waste removal.

Additionally, water plays a critical role in maintaining cell turgor pressure, which is necessary for structural integrity in plant cells. It also helps to stabilize temperature and provides a habitat for many organisms. The unique properties of water, such as its high heat capacity, solvent capabilities, and cohesive and adhesive properties, contribute to its importance in biological functions. Therefore, the statement that water is crucial for biochemical reactions and maintaining cell structure accurately reflects its fundamental role in living organisms.
