The endosymbiosis theory explains the presence of organites in eucaryotic cells by the integration of a procaryote.

Now, me and cell biology is not that good friends, however the statement that two "Two prokaryotic cells combine to produce one eukaryotic cell." sounds a bit miguideing. The theory is very precise discribed by you Ataly, however I fail to see how we can conclude A. Did the very first eukaryotic cell not just envolve out from one prokaryotic cell and then alonge the way integrate prokaryotic cells as organels? If two prokaryotic is combined (I asmuse fussed together) then the cells would still not to stand to do the defintion for a eukaryotic cell. Just some thoughts that passed my mind, however with the options I agree it is A.

@Frostbite You are wright that the theory is a bit more complex (e.g. you need one cell to be much larger than the other so with a protist it would be a better recipient) but in the given choices the option is clear!

@ataly You are absolutly right, as I also conclude saying that with the options only one answer can stand out as the right one. Just tormented my mind to find a link between things.
