Abstract
To understand the biochemical and cytological basis of cell polarity is to gain insight into the process of differentiation. When organisms differentiate, modifications of morphological and functional characteristics occur at certain loci. These loci are specified relative to an axis of polarity. Polar organization of multicellular organisms directs the specialization of previously undifferentiated cells at distinct sites. It is a prerequisite for development of a specialized organism. Without a polar organization there can be no differentiation.
