What Is Water and Why Is It Important?

Water is a simple molecule (H₂O), yet it is one of the most powerful substances on Earth. It covers about 71% of the planet's surface and is essential for all known forms of life. Without water, biological processes would cease, ecosystems would collapse, and human civilization would not exist.

Key Functions of Water

• Supports cellular processes
• Regulates temperature
• Acts as a solvent for nutrients
• Enables transportation within organisms
