The endosymbiotic theory proposes that mitochondria in eukaryotic cells arose from . A. endosymbiotic eukaryotes that metabolized oxygen. B. endosymbiotic eukaryotes that were photosynthetic. . C. endosymbiotic prokaryotes that metabolized oxygen. D. endosymbiotic prokaryotes that were photosynthetic .

The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and endosymbiosis is a type of symbiosis in which one organism lives inside the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialised into mitochondria. That bacteria was able to metabolize oxygen. Inside the cell, after mitochondria evolved as organelle from ingested bacteria, it kept its function to metabolize oxygen.

The endosymbiotic theory proposes that mitochondria in eukaryotic cells arose from endosymbiotic prokaryotes that metabolized oxygen.

Further Explanation:

The two basic kind of organism that are present on the earth are:

1. Prokaryotes

2. Eukaryotes

The prokaryotes do not have well defined nucleus but eukaryotes possess the same. Prokaryotes also lacks the cell organelles such as mitochondria and chloroplast.

The mitochondria is involved in performing the function of cellular respiration. Mitochondria is present in all eukaryotic organisms. The chloroplast is responsible for performing the photosynthesis which occurs in plants and not in animals.

The mitochondria and chloroplast possess their own genetic material. Their genetic material resembles bacterial genetic material. They also have the membrane that resembles to the prokaryotic membrane for example mitochondria has the inner membrane that has folds known as cristae that resembles the prokaryotic membrane that also possess folds known as mesosomes. They divides in the similar manner to the prokaryotic organism.

An endosymbiont theory states that the mitochondria and chloroplast arose from endosymbiotic prokaryotes that metabolized oxygen. These endosymbiotic prokaryotes lives in the symbiotic association of the eukaryotic organism such that the eukaryotes depended on them for their survival.
