title: The living cell as an ecosystem: Hierarchical analog and symmetry.
abstract: Biology has benefited from a number of analogies and metaphors, in its attempt to rationalize the hierarchical structure of life's manifestations. Oft-cited is the comparison of a living organism to a society. Phenomenological similitude between the two extremes of the biological spectrum - the microscale of the cell and the macroscale of socioecosystems - has become strikingly evident, with the recent accumulation of empirical information on the metabolic infrastructure of the living cell. From the universal perspective of 'physiological determinism' reciprocal (or symmetric) relations are apparent at both levels of complexity. Unification of the biological hierarchy may follow a similar epistemological course to that in contemporary physics.
