How can i summarize the endosymbiotic theory for the origin of eukaryotes?
I. Theory of endosymbiosis. A. Introduction 1. Simply stated, the theory of endosymbiosis is the concept that mitochondria and chloroplasts are the result of years of evolution initiated by the endocytosis of bacteria and blue-green algae which, instead of becoming digested, became symbiotic. 2. Alternate theories of the evolution of eukaryotic cells. a) The mitochondria and chloroplasts are developments of the invaginations of the cell membrane. Such that the rest of the cell, being relieved from power house duties, became highly developed and evolved. b) The bacterium some how developed externally, and the casing around the bacterium is now what we call a eukaryotic cell. 3. We will never be able to turn back the clocks, thus we will never be absolutely sure of the correct answer. B. Is it feasible to consider that a bacterium was once ingested by a “eukaryotic cell” such that the bacterium became symbiotic? 1. Some dinoflagellates have been observed to have two nuclei. It is now kno
