Life means various things to different individuals. But nobody really knows life till they know exactly what it is and which structure on the planet is more suitable to carry it on. This article describes Life in functional terms and pinpoints the biological cell as the host of the actual living principle.

First of all, what is LIFE? What is the definition of Life?

According to dictionary. reference. com, Life is: ‘the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally”, among other definitions.

Another definition from the web is from merriam-webster. com/ and it says that life is ” the quality that distinguishes a vital and functional plant or animal from a dead body b: a state of living characterized by capacity for metabolism, growth, reaction to stimuli, and reproduction”, still among other definitions.

Do these definitions explain the reader what life actually is? Maybe so, maybe not.

To define life the way most people can understand exactly what it is we have to think about living organisms and find out what they do differently from non living things.

Life deals with creativity, activity, movement, growth, changes, reproduction, adaptation to ecological limited size, specific form, etc. but those factors aren’t specific to living organisms. If you look carefully you’ll find most of them or all, related to non living things too. What living things do differently from non living things is:

try to experiment many of them instead of only one or a few unlike what we observe in non living things that individually pick up some factors and don’t include others
combine all these factors within a process or a plan towards the accomplishment of personal gaols and hopefully one last goal

Living organisms are part of the Nature. They do not do things that no non living thing cannot do. Thy most of times do things which are done in Nature. But they can do many things again and again following a {plan.

Living organisms work but they are not the only workers on the Planet. Work being the ability to move and/or change things, we know that Water and also the Wind for instance work well similar to how the Sun light will. What living organisms do differently is actually use work to satisfy personal goals and then hopefully transmit this particular work to new living organisms self-made or available. So what is actually Life? How can we now define Life?

Life is just a useful work!

Life is the work done by an element of Earth in order to achieve personal goals which are mainly self-protection, growth, communication, creativity, interactions, adaptation to environment and reproduction/birth.

In practical terms Life is really a process of beneficial assimilation of energy/matter by a so-called living organism. In order to keep living such an organism absorbs external energy/matter, digests it, retains useful elements that more often than not are used to create new specific energy/matter that’s integrated into the body and throws the waste material away. The fact of taking external energy/matter and then put most part of it in its body to ensure that external energy/matter is now intrinsic part of the body is what’s termed the assimilation ability of the living organism. But since that assimilation features a purpose, I call this useful assimilation. So what is actually Life then now?

Life is a helpful assimilation of energy/matter.

How useful is actually this assimilation? It allows the actual living organism to self sustain itself, adapt to environmental surroundings, be more creative, grow if required and reproduce if at all possible.

What are living organisms, those earth elements capable of doing a work termed useful assimilation?

If you look carefully and examine them with scientific tools you will discover that all so-called living organisms are organic cells or society of cells, that is those we call microorganisms (single cells and small communities of cells) as well as animals and vegetation commonly called pluricellular organisms. We can now simply call livings things cell organisms.

To know what Life is about, it remains for people like us to study cells and their existence through individual single cell living and life sharing experiences in huge cellular societies like every one of us!.
