Summary Introduction
The endosymbiotic hypothesis explains the origin of the eukaryotic cells. This hypothesis determines the diversification of the eukaryotic cells. This hypothesis was considered as an evolutionary theory as it explains about the eukaryotic cells origin from the primitive prokaryotic cells. It explained the early existence and the origin of chloroplast and mitochondria in the eukaryotic cells.
