Endosymbiotic theory The modern or organelle-containing eukaryotic cell biology essay
Essay. Views. 1026. The endosymbiotic theory explains the evolution of the eukaryotic cell and eukaryotic organelles by phagocytocis of small prokaryotic cells. This theory states that some organelles in today's eukaryotic cells were once prokaryotic bacteria. In this theory, the first eukaryotic cell, article 'On the Origin of Mitosing Cells' in the Journal of Theoretical Biology by Lynn Margulis and then Lynn Sagan is widely credited with stimulating renewed interest in the long-dormant endosymbiont hypothesis of the origin of organelles. In her article, Margulis not only defended an endosymbiotic origin of mitochondria and plastids, A mitochondrion plural: mitochondria is an organelle in plants, animals and fungi that produces chemical energy for cells. Mitochondria are the powerhouses of the cell. They are unique organelles present in almost all eukaryotic cells and responsible for generating the cell's supply of adenosine triphosphate, ATP, the energy. The endosymbiotic theory. The endosymbiotic theory is a scientific theory that states that some organelles in eukaryotic cells, such as mitochondria and chloroplast, come from free-living prokaryotes, bacteria and archaea. Endosymbiosis is the relationship between two organisms when one is alive. . Fifty years ago, Lynn Margulis (1938-2011), her maiden name was Alexander, and her family name was Sagan. We use Margulis in this article, seminal works published on the endosymbiotic origin of eukaryotic cells: a hypothesis paper “On the origin of mitosing cells In the Journal of Theoretical Biology, Inspecting eukaryotic traits from the perspective of the endosymbiont reveals that eukaryotic cell biology can be explained as a solution for housing a semi-autonomous organelle, and why the addition of another endosymbiont, the plastid, has been added. no extra subjects. Mitochondria provided the selective pressure for the endosymbiotic theory of eukaryotic cell evolution rests on a foundation of three keystone partners: the plastid a cyanobacterium, the mitochondrion a proteobacterium, and its host a proteobacterium..
