Water often has an important role in many chemical reactions; plants react water with carbon dioxide and light energy to produce glucose and oxygen in the process of photosynthesis. A hydrolysis reaction in the human gut allows disaccharides to be broken down into monosaccharides, which involves the addition of a water molecule.
Importance of Water. Water is an essential nutrient and plays a key role in the human body. We can survive up to several weeks without food, but only a few days without water. Every system in the body, from cells and tissues, to vital organs requires water to function.
Water is a vital molecule for the human body. Approximately 98% of the human body is made up of water. Human beings cannot survive if their water content decreases below 12%; hence the homeostasis of water is an important mechanism. Water has many important functions in our body.

All plants and animals need water to survive. There can be no life on earth without water. Why is water so important? Because 60 percent of our body weight is made up of water.
