This paper is about Lynn Marguolis and her discovery of endosymbiosis; the theory that mitochondrias and chloroplasts evolved from bacterias.

EndosymbiosisBefore the 1960s many biologists pondered as to how eucaryotic cells evolved. Some scientists believed that these problematical organisms evolved from prokaryotic cells. However, this conjecture begged the question, why ar prokaryotic cells liquidity functioning if evolution occurred? Darwin?s possible action of evolution come ons against this possibility alone in the 1960s biologist Lynn Margulis medley showed the endosymbiotic theory. This theory she created would wee-wee much(prenominal) evidence to help prove its truth. In 1967, Dr. Margulis hypothesized a theory of eukaryotic evolution. She ?proposed that aerobic bacterium (that contend oxygen) were ingested by anaerobic bacteria (poisoned by oxygen), and may to each one have had a survival emolument as eagle-eyed as they continued their partnership.? (Biology.Com). The endosymbiotic theory states that eukaryotic cells originated from engulfing bacteria (prokaryotic) cells and haveing a symbio tic relationship amongst cells. An zoology cell would band an aerobic bacteria cell to form mitochondria, while a institute cell would surround teal algae to form chloroplast. (Berkley). This theory explains why animals cells are commensurate to perform cellular respiration and plant cells are commensurate to perform photosynthesis. aerophilic bacteria cells and blue-green algae cells are able to hap on their own and create wastes. When the cells were engulfed, the refreshed eukaryotic cells create a symbiotic bond between the two reprint parts.

In a symbiotic relationship, cells eudaemonia from one anoth er. In animal cells the process which benefi! ts both cells is cellular respiration. In plant cells the process is photosynthesis. These sharing cells each have a duplicate of DNA. The actual cells with the nucleus contain a separate imitate from the mitochondria or the chloroplast. (Telic). The DNA is similar but not exact. The endosymbiotic theory shows how cells became independent through phagocytosis. The swallowing of bacteria by a cell allows the new cell to become much more interlacing and self-oriented.
