What is the meaning of life is defined by its chemistry?
Definitions. One definition seems to be favored by NASA: “a self-sustaining chemical system capable of Darwinian evolution”. More simply, life is, “matter that can reproduce itself and evolve as survival dictates”.
What is the basic chemistry of life?
All living organisms use nucleic acids, proteins, lipids, and carbohydrates as their basic building blocks of life, and a variety of small molecules such as metabolites, messengers, and energy carriers.
What is the purpose of life scientifically?
All life forms have one essential purpose: survival. This is even more important than reproduction. After all, babies and grannies are alive but don’t reproduce. To be alive is more than passing genes along.
Why is the chemistry of life important?
Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil. Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems in health, materials, and energy usage.
Why is the chemistry of life special?
There are 118 elements, but only 92 occur naturally. The remaining elements are synthesized in laboratories and are unstable. The polarity of the water molecule and its resulting hydrogen bonding make water a unique substance with special properties that are intimately tied to the processes of life.

What is the definition of life?
First the technical definition. Life is self-organising chemistry which reproduces itself and passes on its evolved characteristics, encoded in DNA. In thermodynamics terms, it has the ability to reduce local entropy or disorganisation, thus locally contravening the third law of thermodynamics.

Do we need a scientific or folk definition of life?
Regardless of whether researchers ever reach a consensus on a scientific definition, we still need a folk definition for practical purposes — a sentence to explain the concept of life that the average person can understand. Life may be a fuzzy concept, but that doesn’t mean its meaning should be vague.
What is the defining feature of life?
An alternative approach is to use the theory considered to be a defining feature of life: Charles Darwin’s theory of evolution by natural selection, the process that gives life the ability to adapt to its environment.
