The question, what is life? Is one that I found to be pretty difficult to answer. Before this class, I would have characterized something as being alive by it being able to grow, breath, move, needing energy to live, and needing food. As I looked over this list I realized that not everything that is alive shares these same characteristics. In class we came up with a better list that seems to cover most, if not all, of what describes a living organism. The list states that a living organism must be bounded, energy dependent, having an improbable assembly, semi-homeostatic, semi-autonomous, and reproduces with variation. I feel that this is a better list than what I originally thought defined something as being alive.
