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 at once prokaryotic cells that lived inside much larger army cells, initially the prokaryotic cells may cast off been parasites. The theory states that the mitchodrion certain from the proteobacteria and the chloroplast developed from the cyanobacteria. The theory holds a lot of evidence display that the mitochondrion and the chloroplast developed from bacteria such as; nouveau-riche mitochondrion and plastids are drawed (such as chloroplast) th close together(p) a process analogous to binary fission which is a realize of cell division use 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 in truth similar to bacter ia in form of shape and size, withal the mitochondrion and bacteria have many an(prenominal) similar enzymes and catch systems.  They also have a double- membrane which might foretell that the innermost membrane is from its days living as a prokaryote.  A publication of points invalidate the endosymbiosis hypothesis: if chloroplasts were once autarkic cells then on that point would have only been hotshot 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 dynamic reticulum, nothing same any bacteria scientists have seen.If you want to get a full essay, order it on our website: OrderCustomPaper.com
