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 convolute organisms evolved from prokaryotic cells. However, this conjecture begged the question, why atomic number 18 prokaryotic cells fluidity functioning if phylogenesis occurred? Darwin?s possible action of evolution stresss against this possibility further in the 1960s biologist Lynn Margulis grade showed the endosymbiotic theory. This theory she created would piddle lots evidence to help prove its truth. In 1967, Dr. Margulis hypothesized a theory of eukaryotic evolution. She ?proposed that aerobic bacteria (that contend oxygen) were ingested by anaerobic bacteria (poisoned by oxygen), and whitethorn to each one have had a survival usefulness as eagle-eyed as they continued their partnership.? (Biology.Com). The endosymbiotic theory states that eukaryotic cells originated from engulfing bacteria (prokaryotic) cells and fixing a symbi otic relationship between cells. An animal(prenominal) 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 fitting to perform cellular respiration and plant cells are satisfactory 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 hot eukaryotic cells create a symbiotic bond between the two reprint parts. In a symbiotic relationship, cells take in from one another. In animal cells the process which benefits 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 swallo! wing of bacteria by a cell allows the new cell to become much more interlacing and self-oriented.
