"Describe the theory of endosymbiosis and the arguments for and against this theory"

Dr Lynn Margulis, a biologist from capital of Massachusetts University, proposed in the 1960s, the surmisal of endo mutualism. It was so officially published in her book Symbiosis in Cell Evolution. The theory suggests that cells originated as communities of interacting entities a could kernel together in a specific order. Organelles same mitochondria and chloroplasts were themselves prokaryotic cells before the development of eucaryotic cells. It was believed that a force cell, credibly similar to amoeba, ingested a smaller cell by phagocytes. They ingested in a way that the soldiery cells are unable to withdraw them and they were allowed to survive. Also, the DNA of the ingested cell would be coded into the boniface cell which causes successive generations they could likewise contain the ingested cell. Margulis as well as predicted if the organelles were really prokaryotic symbionts, they should produce their own DNA and also should resemble that of bacteria and different from the hosts DNA. Mitochondria as aerophilic bacteria, chloroplasts as cyanobacteria... For mitochondria, they previously were like aerophilous bacteria and this takes place in an type Oated environment. The host cell respires anaerobically ingested a cell which respires aerobically. Since more adenosine triphosphate could be produced by aerobic respiration, the host cell could now be provided with more ATP and in return, provide nutrients like glucose to the ingested cell.

quasi(prenominal) for chloroplast, they were previously like cyanobacteria. They were ingested by an aerobic host, after beingness ingested, they continue to photosynthesise. As a result, they provide the host with oxygen and food like glucose and the host would provide the cells with carbon dioxide and due north which are reactants for photosynthesis. This mutualistic interaction mingled with the host and the ingested cell whence became an obligatory symbiosis as the two sides lost roughly of their abilities to function without another. eukaryotic cells like...
