Question

Why is the water molecule so important to organisms?

Answer 1

Water makes up 70-90% of weight of most forms of life; it also represents the continuous phase of living organisms.

Explanation:

it is a highly reactive substance with unusual properties. It is an important determinant of the characteristic structure and biological properties of proteins and nucleic acids, membranes, ribosomes and many other cell components.

Water has a higher melting point, boiling point, heat of vaporization, heat of fusion and surface tension than most common liquids. These properties indicate that its internal cohesion or forces of attraction between molecules in liquid water is high.

Water is also a much better solvent than other liquids.
