Answer:
Theory of endosymbiosis: Symbiogenesis, or endosymbiotic theory, is an evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms
.The endosymbiotic theory describes how a large host cell and ingested bacteria could easily become dependent on one another for survival, resulting in a permanent relationship. Over millions of years ofevolution, mitochondria and chloroplasts have become more specialized and today they cannot live outside the cell.
Theory of endosymbiosis concerns the origin of mitochondria and chloroplasts, two organelles contained within various eukaryotic cells. these organelles originated as separate prokaryotic organisms that were taken inside a primordial eukaryotic cell. Such symbiotic relationships in which two species are dependent upon one another to varying extents served as crucial elements of the evolutionary progression of eukaryotic cells
.
Endosymbiosstudent demonstate the theory of is using the models:
Bacteria are prokaryotes. Bacterium contain no membrane bound nucleus and rarely contain membrane bound organelles. Simply, most don't have any large organelles with their own membranes; this means no nucleus, no mitochondriaand no chloroplast.Small must b more simple or lack mitochondria .while large have mitochondria .Focousing on the presence or absence of mitochondria and chloroplast student demonstrate the theory of endosymbiosis>
