Question

According to the theory of endosymbiosis,

Answer 1

I'm going to base this off of the question I have seen on here a few other times. Mitochondria have two membranes, their outer membrane is more similar to eukaryotic membranes and the inner more similar to prokaryotes.
They have their own circular DNA and replicate by binary fission independent of mitosis.
Chloraplasts and peroxisomes (also part of the endysymbiotic theory) do the same. Less is known of peroxisomes so you might want to leave out that part.

Answer 2

endosymbiosis theory, if i remember it is how a cell became a eukaryotic cell. like the mitchondia i forgot the other organelle. it is said to have just joined the other organelles and another cell to form a more complex cell. but that's all i remember from last year bio.

Answer 3

The endosymbiotic theory argues that mitochondria, plastids (e.g. chloroplasts), and possibly other organelles of eukaryotic cells, originate through symbiosis between multiple micro-organisms. According to this theory, certain organelles originated as free-living bacteria that were taken inside another cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales, the SAR11 clade,[1][2] or close relatives) and chloroplasts from
