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