Polarity Notes:
Polarity is a fundamental property of biological systems. Polarity is defined as the persistent asymmetrical and ordered distribution of structures along an axis. Polarity is all pervading. Polarity allows the development of functional complexity, not only in multicellular organisms, but also in cells and in subcellular structures. Polar organization allows regions having different functions to be physically related in a manner appropriate for integration of function within the whole organism. Increased functional complexity is seen as being of adaptive value; for example, complexity extends the range of an organism by increasing its tolerance of diverse environments.
