Which statement is true regarding all life forms and water?

• A. All life requires water
• B. All life requires oxygen
• C. Not all life requires water
• D. Water is optional for some organisms

Answer: (A)

The statement that all life requires water is accurate because water plays several fundamental roles that are essential for the survival and functioning of living organisms. Water is a universal solvent, facilitating biochemical reactions by dissolving a wide range of substances. It is involved in metabolic processes, including photosynthesis in plants and cellular respiration in animals. Additionally, water helps maintain cellular structure and function due to its role in providing turgor pressure in plants and maintaining the shape of cells in all living beings. While some extremophiles, such as certain types of bacteria and archaea, can survive in extremely dry conditions or can metabolically adjust to conserve water, they still rely on water for reproduction and growth under normal conditions. Therefore, all known forms of life on Earth require water in some capacity to sustain their biological processes, making the statement true.
