Functional Characteristics of Life:
* Organization: Living things are highly organized, with cells as the basic unit of life. They have specific structures (organs, tissues) that carry out specialized functions.
* Metabolism: All living organisms require energy to sustain life. Metabolism encompasses all chemical reactions that occur within a living organism, including breaking down food for energy and building complex molecules.
* Growth: Living organisms increase in size and complexity over time.
* Adaptation: Living things change over generations to better suit their environment. This is driven by natural selection.
* Response to stimuli: Living organisms react to changes in their environment. For example, plants bend towards sunlight, and animals flee from danger.
* Homeostasis: Maintaining a stable internal environment despite external fluctuations (e.g., body temperature regulation in mammals).
* Reproduction: Living organisms produce offspring to ensure the continuation of their species.
What wouldn't be a functional characteristic of life?
The ability to create life from non-living matter. This is the definition of abiogenesis, which is the origin of life from non-living matter. While we know life exists, the exact process of abiogenesis is still a scientific mystery. Current life doesn't create life from scratch.
