"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 possibility 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 centre together in a specific order. Organelles same mitochondria and chloroplasts were themselves procaryotic cells before the development of eucaryotic cells. It was believed that a soldiers cell, likely similar to amoeba, ingested a small cell by phagocytes. They ingested in a way that the army cells are unable to tolerate them and they were allowed to survive. Also, the DNA of the ingested cell would be coded into the military cell which causes accompanying generations they could overly contain the ingested cell. Margulis in addition predicted if the organelles were really prokaryotic symbionts, they should fall in their own DNA and also should resemble that of bacteria and antithetic from the hosts DNA. Mitochondria as aerobiotic bacteria, chloroplasts as cyanobacteria... For mitochondria, they previously were like aerophilous bacteria and this takes place in an atomic number 8ated 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.

akin(predicate) for chloroplast, they were previously like cyanobacteria. They were ingested by an aerobic host, after cosmos 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 northward which are reactants for photosynthesis. This mutualistic interaction betwixt the host and the ingested cell so became an obligatory symbiosis as the two sides lost around of their abilities to function without another. eukaryotic cells like...
