what is the endosymbiotic theory
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.
Report Abuse. The Endosymbiosis theory is about chloroplasts and mitochondria and their two membranes. First there are two prokaryotic cells, chloroplast and mitochondria, then one of cells dulges into the other cell and they create a second membrane.Chloroplast and Mitochondria.eport Abuse.
