Describe Endosymbiosis and the Origin of Eukaryotic Cells.

2. Endosymbiosis and the Origin of Eukaryotic CellsEndosymbiotic theory, first proposed by Konstantin Mereschkowski in the early 1900s, explains the origin of eukaryotic cells. Your classmate is having a hard time understanding how endosymbiosis can explain the origin of organelles in eukaryotic cells. Write a one to two-page summary that explains to your friend what the Endosymbiotic theory is, the proposed mechanism for the development of eukaryotic cells and the origin of organelles, and the evidence supporting the theory.
