Document Summary
They are made up of one or more membrane-bound units called cells. They store and process information that is heritable. As populations, they evolve (meaning they change) The cell theory states that all organisms are made of cells (pattern), and all cells come from pre-existing cells (mechanism). Within a multicellular individual, all cells are descended from a progenitor cell the zygote. In general, cells contain molecular information (dna) that encodes their physical attributes (through some cells loose their dna). Cells have a boundary between them and the environment. Cells have the ability to harness materials and/or energy. Because viruses cannot independently replicate or independently harness energy, they are not considered to be living organisms, even though they do have dna. Chemical gradients can be used to store energy. Links a phenotype to the same space as genotype that encodes it. How many genes influence phenotype (less genes = earlier)
