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 eukaryotic cells evolved. Some scientists believed that these meandering(a) organisms evolved from prokaryotic cells. However, this conjecture begged the question, why argon prokaryotic cells liquefied functioning if maturation occurred? Darwin?s possible action of evolution put forwards against this possibility just in the 1960s biologist Lynn Margulis modification showed the endo dependent opening. This possibility she created would keep back more than 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 anaerobiotic bacteria (poisoned by oxygen), and may to each one fix had a survival reward as eagle-eyed as they continued their partnership.? (Biology.Com). The endosymbiotic theory states that eukaryotic cells originated from engulfing bacteria (prokaryotic) cells and figing a symbiotic relationship amid cells. An living organism cell would band an aerobic bacteria cell to form mitochondria, while a show cell would surround blue green algae to form chloroplast. (Berkley). This theory explains why animals cells are sufficient to perform cellular respiration and plant cells are adequate to(p) 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 take in from one another. In animal cells the work at which benefits both cells is cellular respiration. In plant cells the process is photosynthesis. These sharing cells each have a duplicate of DNA. The unfeigned 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 self-sustaining through phagocytosis. The swallowing of bacteria by a cell allows the bleak cell to become often more interlacing and self-oriented.
