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 once 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 regular(a) from the proteobacteria and the chloroplast developed from the cyanobacteria. The theory holds a lot of evidence demo that the mitochondrion and the chloroplast developed from bacteria such as; upstart(a) mitochondrion and plastids are mental strained (such as chloroplast) th around a process analogous to binary fission which is a imprint of cell division use by all prokaryotes cells and rough eukaryotic cells. Mitochondrion and chloroplast cells to a fault lead deoxyribonucleic acid that is various to a cell nucleus but genuinely similar to bacteria in form of shape and size, in addition the mitochondrion and bacteria have many an(prenominal) similar enzymes and pack systems.

 They also have a double- membrane which might testify that the innermost membrane is from its days living as a prokaryote.  A publication of points invalidate the endosymbiosis hypothesis: if chloroplasts were once breakaway cells then on that point would have only been wizard 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 the ir shape and size ,thirdly their division is! quite different. Mitochondria form in a labyrinthian and dynamic reticulum, nothing handle any bacteria scientists have seen.If you want to get a full essay, order it on our website: OrderCustomPaper.com
