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 rowerly prokaryotic cells that lived inside much larger army cells, initially the prokaryotic cells may cast off been parasites. The theory states that the mitchodrion positive from the proteo bacterium and the chloroplast developed from the cyanobacteria. The theory holds a lot of evidence viewing that the mitochondrion and the chloroplast developed from bacteria such as; pretentious mitochondrion and plastids are yeared (such as chloroplast) th uncouth a process analogous to binary fission which is a form of cell division apply 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 very(prenominal) similar to bacter ia in form of shape and size, similarly the mitochondrion and bacteria have many an(prenominal) similar enzymes and outrage systems.

 They also have a double- membrane which might signalize 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-lance cells then on that point would have only been nonpareil 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 t heir shape and size ,thirdly their division ! is quite different. Mitochondria form in a labyrinthian and dynamic reticulum, nothing worry any bacteria scientists have seen.If you want to get a full essay, order it on our website: OrderCustomPaper.com
