Symbiogenesis, or endosymbiotic theory, is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes.It states that several key organelles of eukaryotes originated as a symbiosis between separate single-celled organisms.ccording to this theory, mitochondria, plastids (for example chloroplasts), and possibly other organelles representing formerly free-living bacteria (prokaryotes) were taken inside another cell as an endosymbiont around 1.5 billion years ago.
Best Answer: Endosymbiosis is the idea that certain organelles found in eukaryotic cells today, like mitochondria and chloroplasts were originally separate organisms which were absorbed into early eukaryotic cells and had a symbiotic relationship with them.ver time, they evolved along with the cells until they were fully part of the cell and no longer self-sufficient organisms. The best piece of evidence for this theory is that chloroplasts and mitochondria have their own DNA, which is different than the DNA stored in the nucleus.
