Endosymbioses: Evolutionary Trends in Cellular Compartmentation
Ultrastructure of eukaryotic cells is characterized by compartmentation, e.g., by the existence of special areas surrounded by membranes. These areas have special functions in cell metabolism and are partially endowed with their own genetic apparatus which is different from the nuclear one. This discontinuity in cellular organization has been intriguing to biologists since the beginning of microscope studies, and has initiated many speculations on development of eukaryotic features. Two main hypotheses trying to explain compartmentation are being discussed nowadays:
endogenous differentiation of membrane enclosed areas (Cavalier-Smith 1981) and
uptake of foreign cells and subsequent symbiosis formation (endosymbiotis theory) (Margulis 1981).
