The endosymbiotic theory to explain the origin of which structures

Endosymbiotic theory explains that the eukaryotes and the prokaryotes have the same ancestor. It explains their theory on the basis of mitochondria and chloroplast structure.

Further Explanation:

The endosymbiotic theory describes that life emerges on earth nearly around four billion years ago. It also explains that prokaryotes, as well as eukaryotes,evolved from the same ancestor. There is evidence that the first eukaryote might be similar toan amoeba that engulfs their food by phagocytosis. It is stated that the organisms (amoeba) may have ingested the prokaryotic cells that may have survived within the organism that leads toa symbiotic relationship.

The mitochondria were formed or developed when the organism engulfs the microbe which is capable of cellular or aerobic respiration. The chloroplast wasalso developed from the same process. They lose their cell wall as well asa certain part of the DNA because there was no use of it. Mitochondria and chloroplast are not able to grow outside the host cell. They have their own DNA that is circular in structure and they also possess their own ribosomes.

If we break down the word literally, "endo" means into or inside and "symbiotic" means working together. explains the origin of eukaryotes much better.Overview of the Process of Endosymbiosis. Evidence for Endosymbiosis. Mitochondria and chloroplasts are both organelles suggested to have arisen via endosymbiosis. Evidence that supports the extracellular origins of these organelles can be seen by looking at certain key featuresThe endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. According to this theory, these originated as prokaryotic endosymbionts, which came to live inside eukaryotic cells. The theory postulates that the mitochondria evolved from…

There are points in which they have been found in favour, but others that Evidence is also found in its structure. The mitochondria and chloroplast have a double membrane. This could be due to its origin, being the interior the membrane…PDF | For over 100 years, endosymbiotic theories have figured in thoughts about the differences between prokaryotic and eukaryotic cells. More than 20 different versions of endosymbiotic theory have been presented in the literature to explain the origin of eukaryotes and their mitochondria.The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.

Endosymbiotic theory – The endosymbiotic theory is the accepted mechanism for how eukaryotic cells evolved from prokaryotic cells. It involves a cooperative relationship between two cells During Margulis' research on the origin of eukaryotic cells, she studied data on prokaryotes, eukaryotes, and organelles, finally…The endosymbiotic theory concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. The endosymbiotic theory was first articulated by the Russian botanist Konstantin Mereschkowski in 1905[1]. Mereschkowsky was familiar with work by the…The endosymbiotic theory concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms that were taken inside the cell as endosymbionts.
