Cell Theory: There are three parts to cell theory — 1) the
cell is the basic unit of life 2) All living things are composed
of cells 3) All cells arise from pre-existing cells.
Energy: All living things require energy and energy flows
between organisms and between organisms and the
environment.
Heredity: All living things have DNA and genetic
information codes the structure and function of all cells.
Equilibrium: All living things must maintain homeostasis, a
state of balanced equilibrium between the organism and its
environment.
Evolution: This is the overall unifying concept of biology.
Evolution is the change over time that is the engine of
biological diversity.
