The Endosymbiotic theory was first proposed by airer Boston University life scientist Lynn Margulis in the 1960s, the theory states that the organelles mitochondrion and chloroplast and possibly other organelles of  eucaryotic cells were in ane case prokaryotic cells that lived inside much larger army cells, ab initio the prokaryotic cells may cast off been parasites. The theory states that the mitchodrion mathematical from the proteo bacterium and the chloroplast developed from the cyanobacteria. The theory holds a lot of evidence screening that the mitochondrion and the chloroplast developed from bacteria such as; pretentious mitochondrion and plastids are gradeed (such as chloroplast) th roughly a process analogous to binary fission which is a play of cell division utilize by all prokaryotes cells and rough eukaryotic cells. Mitochondrion and chloroplast cells to a fault lead desoxyribonucleic acid that is various to a cell nucleus but actually similar to bacteria in form of shape and size, in addition the mitochondrion and bacteria have many an(prenominal) similar enzymes and tape drive systems.

 They also have a double- membrane which might denominate that the innermost membrane is from its days living as a prokaryote.  A publication of points invalidate the endosymbiosis hypothesis: if chloroplasts were once free cells then on that point would have only been one outcome, the cell would have been digested by the parent cell and used as food, the digestive enzymes would have destroyed it. Also mitochondria do not have many things in common with bacteria except of their shape and size ,thirdly their division is quite different. Mitochondria form in a labyrinthian and dyn! amic reticulum, nothing handle any bacteria scientists have seen.If you want to get a full essay, order it on our website: OrderEssay.net
