2 Defining a living organism The cell is the minimal unit of life that has all the properties of being alive. Much if not most of the biomass on Earth is unicellular; and, as we shall see, on many if not most other worlds, the majority of living things may well be at least microscopic, if not unicellular. We use the term "organism" in this book to include both unicellular and multicellular forms of life. All the organisms that exist on Earth, and those that will compose our speculative populations on other worlds, have three features that define them as living entities : First, they consist of discreet beings enclosed by physical boundaries that separate their highly organized interiors from the surrounding environment.
T h e Life Unseen m o d e l In its starkest form, the Life Unseen Model states that the life we can't see is the life that is most common and most typical in the universe. We as humans can't see it with our naked eyes because it's too small. We know it exists, though, because we can see it through a microscope, and we can study its biochemistry and metabolism through a variety of elegant techniques. Rare Earths and Life Unseen 11 The unseen world of life on Earth turns out to be far more massive, widespread, variable, and adaptable than those forms of life that garner most of our attention most of the time.
In summary, the many carbon compounds that are hydrophilic can dissolve readily in water and engage in all the intricate dances of life, while those carbon compounds that are hydrophobic form solid barriers that resist the passage of water and other molecules through them, providing the enclosures and boundaries required by our definition of living systems. At this point, we need to consider whether silicon, carbon's larger sibling in the same column of the periodic table, has the power and versatility to support a different biochemistry of its own.
