    The cell theory‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Any organism that is composed of similar units of organization is a cell. Matthias Schleiden and Theodor Schwann proposed the cell theory. Biological classification is the classification of living organisms. Bioenergetics is the theory that the same energy powers both living and inanimate objects.
