Biologist Lynn Margulis first proposed the philosophy of endosymbiosis in the 1960s ("Endosymbiosis and The Origin of Eukaryotes", 2016) revealing that other cellular organelles such chloroplasts, as being similar to mitochondria.This includes their self-replicating ability and a double mellbrane accompanying their ribosomes and DNA. Such evidence suggests, Chloroplast organelles were also once f8-living bacteria ("Endosymbiosis and The Origin of Eukaryotes", 2016). Given that the first eukaryotic cell evolved monGan a billion years ago (Cooper, 2000) these organelles are now entirely reliant on their host cells. For instance, many integral proteins are delivered from the rest of the cell to the mitochondrion whilst the genes that code these
