- At heart, all life on Earth uses a membrane that separates the organism from its environment. To stay alive, the organism takes in important materials for making energy, while shuttling out toxic substances such as waste products. In this regard, water is essential simply because it's a liquid at Earth-like temperatures.

3 days ago · Big Ideas: All living things need water. Water is critical to cellular function, chemical reactions, and thermal regulation. Water is less dense when a solid and stays in the same state over a wide temperature range. It is abundant on Earth and a common thread between all living things.

Water is so good at dissolving substances that it is known as the ‘universal solvent’. While other substances have similar dissolving power to water, they do not have its chemical stability and its ability to neutralise strong acids and bases.
May 19, 2021 · All living things need water to survive, but what exactly makes water so important? To begin, water helps human bodies transport nutrients and oxygen. The intestines absorb the water and it, as body fluids, goes through the body to give cells nutrients and oxygen and to remove waste products.
Water in its liquid state is needed by all living things. Hydrogen bonds also cause water to expand when it freezes. This, in turn, causes ice to have a lower density (mass/volume) than liquid water.
Earth's water is always in motion. It moves inside the planet, across its surface, and in the atmosphere above. Water in lakes, rivers, and oceans turns into vapor and moves into the air through evaporation. Plants draw water from the soil and return it to the air.
